IRIX and Software

Yeah, my apologies for using the unmaintained autotools. The errors obtained from it seemed easier (to me at least.. and I am not at all a developer) than the ones I got from cmake.

Ah well, if you go that route, you'll have to fix the Makefiles first. What errors did you get the cmake way?

Procedure for not using cmake:
I ran autogen.sh.

The following are my 'hacks' to get this to compile. Very poorly done, and I make no assumptions as to these approaches being valid.

With a custom cmake 2.8.6.. where cmake 2.8.6 itself compiled clean for me... it is not part of our official nekoware distribution which uses an older version.

cmake version 2.8.6

However, I get no Makefile in the build dir.
I believe Dexter1 may have gotten farther down this path with cmake.
I took the one that looked easier with autogen

I think I know the cmake problem — Travis CI or Appveyor hit something similar or identical. Checking ... yeah, odd cmake version, this was the fix:
sed -i 's,\(FIND_PACKAGE.*\) MODULE,\1,' CMakeLists.txt # just removing the MODULE parameter

since I guess your sed doesn't have -i, use redirection or edit the file manually (just three hits).

I'll go play with moved time.h and some of the rest.

oh, you can pass -DDISABLE_WERROR=1 to ...

does IRIX have stricmp instead of strcasecmp?

... yeah, cmake 2.8.8 introduced MODULE. If you refetch git HEAD (git pull), you should be able to run cmake without errors without mods.

Your sed command did it nicely!

Ill see how far this build goes now. (using cmake and gcc)
FYI, IRIX may be an old OS, but with our nekoware package distribution we still have relatively modern apps.. such as sed with -i.
Thanks again for all your help, and being involved all this time trying to help!

man 3 strcasecmp
string(3C) string(3C)

NAME
string: strcat, strdup, strncat, strcmp, strncmp, strcpy, strncpy,
strlen, strchr, strrchr, strpbrk, strspn, strcspn, strtok, strstr
strcasecmp, strncasecmp, index, rindex, strtok_r - string operations

SYNOPSIS
#include <string.h>

I do not believe IRIX has stricmp.. however I will leave that answer to ones more knowledgeable. Googling seems to say IRIX does not and I couldn't find a manpage for it. Running a find/grep within /usr/include didn't find any stricmp either.

ok, so it's just a case of missing includes then.

So taking the same source package that I had the mods indicated earlier (mostly includes).. but of course all the 'Makefile' mods I made are irrelevant when using cmake now.

Your cmake fix:
sed -i 's,\(FIND_PACKAGE.*\) MODULE,\1,' CMakeLists.txt

Build:
cd build
cmake -DDISABLE_WERROR=1 ..

It goes to 72% to where it wants to compile BIKPlayer.
GetBitContext.cpp:52:56: error: 'ldexpf' was not declared in this scope
Rather than debug that.. I assume it could be skipped?
I created a stump BIKPlayer.cpp file that does nothing but had the main function BIKPlayer::BIKPlayer(void)
{ }; and the last few lines in the file (GEMRB_PLUGIN(), END_PLUGIN(),etc..
I edited BIKPlayer's CMakeLists.txt so it only uses BIKPlayer.cpp and no the other cpp files in that dir

The butchered code above does let it continue building.
Then it complained of OpenAL. That one was far more simple just commenting out everything in the related plugin directory CMakeLists.txt (there is an IF Clause in there). I could have simply removed OpenAL libs and headers before running cmake.. maybe ill try that next. Is there another way to force it to not compile OpenAL?

I took BaldursGate1 content from a working Solaris10/SPARC environment and placed on IRIX: so the cfg file and content exist.
#Note, I did try with the -c test.cfg too.. same result

Through process of elimination .. GUIScript.so plugin is what is causing the core dump.
There are 41 plugins.. if I have 40 there.. and remove GUIScript.so.. gemrb loads all and then says it needs GUIscript but no core dump. If I only have 1 plugin available.. and the other 40 removed, gemrb core dumps (and tried different combos).

I noted that Dexter1 has a few more mods left on stricmp change to strcasecmp within GUIScript.cpp .. I'm trying those now. Strange that GCC didnt complain on compiling with stricmp.

ldexpf is C99 and maybe a glibc extension. BIKPlayer is only needed for iwd2 movies though. I'll just disable the whole plugin build if the function isn't available — too lazy to find a reliable standalone implementation (could be tricky, since floats are involved).

What was the problem with openal? You can disable it through ccmake or passing a flag.

We use strcasecmp everywhere but on windows (stricmp is its alias).

The GUIScript plugin is essential. Can you post your current "git diff" the next time?

git diff is attached.
my apologies for it being messy. Its size is mainly due to deleting a large chuck of BIKPlayer.cpp to get it to compile but have it do nothing/dummy. Also GemRB.cpp shows up as modified.. but it really was not.. i was testing things around where gdb was saying it was crashing at.
I also started adding in Dexter's changes you had listed at http://sprunge.us/TPJi?diff but so far I see no difference regarding the GUIScript plugin core dump.

I've pushed some changes, so you don't have to hack BIKPlayer away anymore. Or CMakeLists.txt for the module stuff.

Are the FP constants really needed in both headers?

stricmp is just a macro, so WTF do you need to change the uses?
#ifndef WIN32
# define stricmp strcasecmp
# define strnicmp strncasecmp
#endif

you can run git checkout dir/asd/asd/file to reset your copy of a file to what is upstream. Do that for CMakeLists or you'll get conflicts when updating. So something like
git checkout CMakeLists.txt
git checkout gemrb/plugins/BIKPlayer/*
git stash
git pull
git stash pop

So I did a fresh clone from GIT.. still a few things to adjust/mod but nothing serious (same things mentioned before). My git clone didnt seem to have BIKPlayer removed yet, but it could just be my doing.

Compile works. I was using -O3 before.. but I just tried with the default -O2 optimziation for Gemrb and same thing.

Gemrb loading GUIscript Plugin has the IRIX OS itself terminate gemrb as identified in the IRIX console:

ALERT: Process [gemrb] 487180 generated trap, but has signal 10 held or ignored
epc 0x617f98 ra 0xace67b4 badvaddr 0xfffffffffffffffd
process has been terminated to prevent infinite loop

If I remove GUIScript plugin from the plugins dir.. things load up promisingly .. even an SDL window, and loading BG data files... just needs GUIScript in the end.

What I can do is try with SGI's native MIPSPro Compiler as Dexter did earlier. Just that compiler can be pretty picky. Other than that, im running out of options.

if you run "git log", what is the last commit? You definitely shouldn't need all the hacks from before.

lynx.. dont use any diff files and info from this message to formally add to GemRB. I need more help on this one from Dexter or other more seasoned IRIX developers.

Ok. I am able to compile with MIPSPro Compiler. However the result is unresolvable symbols:

I can find those symbols using 'nm' on libgemrb_core.so.0.8.4-git itself but they seem to be 000000 's? Maybe not built or linked right.

Below is more for Dexter.. when his holiday parties are over:
git clone git://github.com/gemrb/gemrb.git
apply patches from git-diff-mipspro.txt #see attached
Use cmake 2.8.6 or newer (the link to neko_cmake-2.8.6.tardist is earlier in this thread)
I created a custom inittypes.h for va_list:
diff -urp /usr/include/inttypes.h-ORIG /usr/include/intty
pes.h


MIPSPRO ENVIRONMENT


cd gemrb
mkdir build
cmake -DHAVE_LDEXPF=0 -DDISABLE_WERROR=1 ..
# Note that OpenAL bits are commented out as detailed in the DIFF file
gmake VERBOSE=1 install

It will fail later on linking CXX executable gemrb

I worked around this (probably part of the problem):
RUN (its part of the failed command.. this creates the relink.txt):
cd /tmp/gemrb2/gemrb/build/gemrb && /usr/nekoware/bin/cmake -E cmake_link_script CMakeFiles/gemrb.dir/relink.txt --verbose=1

##I found all the missing symbols from c++init.o and -lc -lC -lCio -lSgm .. maybe these are incorrect?

gmake VERBOSE=1 install

builds to 100% but then link error

RUN (its part of the failed command.. this creates the relink.txt): cd /tmp/gemrb2/gemrb/build/gemrb && /usr/nekoware/bin/cmake -E cmake_link_script CMakeFiles/gemrb.dir/relink.txt --verbose=1

gmake VERBOSE=1 install # as root, or use DESTDIR=/tmp/blah
DONE

Thats the best I can get with MIPSPro..
Now, the changes listed in this message/DIFF file.. seem to make GCC not compile now. I did feel a bit closer to the end with GCC

Holy cow, That is some material to sift through!

I have my O2 installed with neko_python-2.7.3 neko_sdl-1.2.13 and a fresh cmake 2.8.12.2 prepped for compiling gemRB this evening, so i'll start producing some stuff this week.

I've started gemrb-0.8.4 compile on my O2 and found a solution for the Holder.h problem

Well, basically this:


TLDR:
cc-1367 CC ERROR "A pointer to an incomplete class type is not allowed."
Initially i didn't know how to proceed, so i commented the problematic functions out. But working on this error message proved fruitful after a couple of hours. The problem lies with the definition of Symbol in gemrb/core/Interface.h :


MIPSPro has its own way of instantiating templates. On occasions where people use forward declaration for classes and then trying to use them with templates produces compiler errors. This is because for template instantiation the class SymbolMgr is different from the class in the header file i.e. it won't see the class definition in the header file.

There are compiler options for remedying this, but why use forward declaration in the first place?
IIRC these are only needed for circular dependencies in class definitions. If it is not needed then don't use it.

I've re-enabled the headers by this diff:


and solved the compile problem.
