Updated GCC Builds
« on: May 02, 2021, 10:43:13 am »
Hi All,

I got a announcement email for GCC 11.1.0 last week, which reminded me I hadn't produced any GCC builds for some time..

Anyhow, with not too many brain cells burned out, I ended up with:

https://smedley.id.au/tmp/gcc-10.3.0-os2-20210502.zip
https://smedley.id.au/tmp/gcc-11.1.0-os2-20210502.zip

Both have been tested only as far as being able to build themselves.

No gccenv.cmd or anything included, it's expected if you want to play with these, you know what you're doing :)

Cheers,

Paul

Tried building FFmpeg with GCC 11.1.0, didn't get too far. I have a trp file but without any debug info or xqs files it is pretty useless. Need at least the map files.
Code: [Select]
Killed by SIGSEGV

Process dumping was disabled, use DUMPPROC / PROCDUMP to enable it.
gcc: internal compiler error: Segmentation fault signal terminated program cc1
Please submit a full bug report,

BTW, trying to use the script that KOMH posted years ago fails as it doesn't like localxx instead of localxxx. I set things up manually and hopefully didn't screw up.

OK, that seemed to be user error, needed to do s/i386//i686/g in my script to set up the environment.
edit: Or maybe not as I ended up with the same crash

10.3.0 succeeded at compiling FFmpeg, I'll have to double check my 11.1.0 install and retest later.

Thanks Paul.  Really cool to see a GCC 11 on here!


I grabbed the 11.1 build and tried to get it to work with cmake, and ran into an error in the "trycompile" phase where cmake introspects the compiler by building things.

Here's how to reproduce it:
https://github.com/wwiv/os2/blob/main/tests/cmake/readme.txt

Hope this helps.

I tried this, keep getting errors involving the environment. I'm not used to cmake and did try setting these environment variables

Thanks. Here's what I tried with the cc11.cmd to set CC and CXX (so cmake can find it).  This assumes the GCC 11.1 stayed in \usr\local11

Code: [Select]
set CXX=C:\usr\local11\bin\g++
set CC=C:\usr\local11\bin\gcc

cmake --debug-trycompile  ..

Code: [Select]
set CXX=C:\usr\local11\bin\g++
set CC=C:\usr\local11\bin\gcc

OK, that works fine. For 11.1.0,
Code: [Select]
[K:\work\os2\tests\cmake\_b]cmake --debug-trycompile ..
debug trycompile on

With similar output for 10.3.0. My guess is that you didn't set up your environment correctly. Here's my gcc11env.cmd.
Code: [Select]
set PATH=W:\usr\local11\libexec\gcc\i686-pc-os2-emx\11.1.0;W:\usr\local11\bin;%PATH%
set BEGINLIBPATH=W:\usr\local11\lib;W:\usr\lib;%BEGINLIBPATH%
set LIBPATHSTRICT=T

set LIBRARY_PATH=W:/usr/local11/lib/gcc/i686-pc-os2-emx/11.1.0;W:/usr/local11/lib;W:/usr/lib;%LIBRARY_PATH%
edit, fixed gcc11env.

Your guess was spot on.  I missed that step since I didn't need it for the built-in GCC didn't think to setup the environment for 11.  Thanks for the help!

Gcc 9.2.0 seems to produce and link

in both
Code: [Select]
\gfx\thebes\Unified_cpp_gfx_thebes0.obj
\gfx\thebes\Unified_cpp_gfx_thebes1.obj

whereas 10.3.0 only has the symbol in thebes0.obj

I guess I'd need to try a local build to work out what's happening. gcc -S output from 9.2.0 and 11.1.0 might be interesting, as would gcc -E output of \gfx\thebes\Unified_cpp_gfx_thebes1.obj - as that might allow me to compile it locally....

Cheers,

Paul

Yes, it looks similar. I went on to build FFmpeg with 10.3.0 so overwrote my trp.
As for SeaMonkey and 10.3.0, I found this in the log,
Code: [Select]
32:51.04 Y:/work/cc45-git/mozilla/gfx/thebes/gfxFont.h: In constructor 'gfxShapedWord::gfxShapedWord(const uint8_t*, uint32_t, int32_t, int32_t, uint32_t)':
32:51.04 Y:/work/cc45-git/mozilla/gfx/thebes/gfxFont.h:1277:72: warning: 'void*memset(void*, int, size_t)' clearing an object of non-trivial type 'class gfxShapedText::CompressedGlyph'; use assignment or value-initialization instead [-Wclass-memaccess]

So I added -Wclass-memaccess to CXXFLAGS (actually the optimize parameter) and that fixed the missing symbol.
Now the compile dies while linking xul.dll with a Python OSError (Errno 22), which I believe is a failure to pass the list file to emxomfld. We're linking over a 1000 object files.
Had the same or similar problem with GCC 9.2.0 and I worked around by creating my own list(response) file and manually calling emxomfld until Dmitriy fixed it sometime later.
IIRC, the problem with 9.2.0 was actually nested response files and was one of the last fixes for 9.2.0

Ok, more investigation into the SM linking issue. I rebuilt with GCC 9.9.2 and then compared the linking between 9.9.2 and 10.3.0. As far as I can make out, the difference is 9.9.2 just passes the list file to the linker while 10.3.0 passes the list file and the list of obj files to the linker, which pukes on such a long command line. The list files produced by both the compilers are identical at 53777 bytes and 1204 lines (obj and lib files).
I'll attach the xul build logs from both, both done after a make clean.
edit: added list file with txt extension for completeness
