Games with older SDL and FSLIB

[Dave Yeo]

Hi Martin, pushed my changes. The package looks fine except I've updated the executable to use -Zhigh-mem, attached.

[Martin Iturbide]

Hello Dave

The older one is working fine, this new one gives me an error that can not find data/sounds.

Hello Dave

The older one is working fine, this new one gives me an error that can not find data/sounds.

Regards

Guess I should have tested
It's weird as the error is,

Code Select Expand


H:\cuyo-2.1.0>cuyo.exe
Error: Could not find "sounds/leftright.wav".
Tried the following places:
  ./data/sounds/leftright.wav

And

Code Select Expand


H:\cuyo-2.1.0>ls ./data/sounds/leftright.wav
./data/sounds/leftright.wav


So it is there and should work.
Hmm, rebuilding without -Zhigh-mem and it works. Just use the original binary as it seems the -Zhigh-mem is breaking something, perhaps the combination of a GCC binary and OW DLL.
Edit: updated compile.os2 removing the -Zhigh-mem

[Martin Iturbide]

Thanks Dave

I uploaded the package to Hobbes (the version that was working fine).

Just for my own learning, how do you run the automake script for this case? In case I want to have a compile.cmd command, what would you include there?

Regards

[Dave Yeo]

In this case and many others, simply

Code Select Expand

sh autogen.sh
Sometimes autogen.sh runs configure at the end so you can pass the configure arguments to autogen.sh.
If you look at Cuyo's autogen.sh, you see the usual minimal autotools series of commands. Some also have libtool.
Once it has been run to use our autotools port, it usually doesn't need to be run again and configure takes care of creating the makefile's from the makefile.in's, which were created by automake from the makefile.am's
So basically configure --arguments, then make for Cuyo and most autotools projects.
for GAME-SDL-PUZZLE-Cuyo, see compile.os2,

sh ./configure --disable-nls --with-sdl-prefix=H:/tmp/SDL 'LDFLAGS=-Zomf' 'LIBS=-lz -lintl'
make pkgdatadir=./data

Of course SDL needs to be setup for GCC as explained earlier in the thread and the above adjusted for your environment.

I'm not sure what can be wrong. I have a different SDL1 path just in case.

Hi Martin, here is the error,

Code Select Expand


configure:3256: checking whether the C++ compiler works
configure:3278: eval g++ -Wall -W -ansi   -Zomf conftest.cpp -lz -lintl >&5
weakld: cannot open library file 'C:\usr\lib\intl_s.a'.
emxomfld: weak prelinker failed. (rc=8)
configure:3282: $? = 1
configure:3323: result: no


No -lintl, or rather intl_dll.a. Libintl is part of gettext so you need to install the gettext-devel package. You will also need the zlib-devel package for libz (libz_dll.a)
Missing libraries on our system usually result in weakld looking for the static version in /usr/lib.

I changed the --cflags section as some projects look for SDL.h and others for SDL/SDL.h

Thanks for the info Dave.

It seems that my SDL into configured right. I will try it your way and see if I can learn something 

If you have the time can you please check the next in line Enigma, to see if it compiles?

Anyways, created the missing files, put them in both directories that had a configure script, autoreconf worked.

checking for current Xerces release 3.0... not found
checking for old Xerces release >=2.4... configure: error: Xerces >= 2.4 not found.


Building Xerces 3.3.0 (from https://xerces.apache.org/xerces-c/download.cgi) things went very smooth until the linking stage where I seem to have run into a bug or deficiency in our build system.
I'll attach the build.log, def file and map file.
Using fc/2 to search for one of the symbols copied from the map file also fails though it is there. They're huge symbols.

[Dave Yeo]

So continuing to work on Xerces-c. I built a static lib, which succeeded. Enigma's configure wasn't happy with it, no main or was it mainl, I lost the log.
Tried using ilink v5. Got similar weakld errors and 2936 errors, all undefined exports.
Then I tried the cmake build. I've had a recurring problem where after running cmake, the makefile seems to recurse at the beginning and locks the system hard. So I tried using ninja instead of make.
This actually built an xerces33.dll. The import lib unluckily was empty, well 8 bytes containing !<arch>. Trying 
"emximp -o xerces-c_dll.a xerces33.dll" resulted in the same import lib. Looking at the def file, we have,

No exports. Frustrating as the dll seems to have exports. It's 5.2 MB's and I wonder if the build system tried to use declspec(export) or whatever the command is.
Failures were all trying to link executables.
Not sure where the object files are either, they don't seem to be in build/

did you adjust

    set(XERCES_PLATFORM_EXPORT "__declspec(dllexport)")
    set(XERCES_PLATFORM_IMPORT "__declspec(dllimport)")

Hi all,
Silvan ported xerces-c 3.3.0 to OS2.
This will be available on monday as RPM

Kind regards,  Tellie

I thought there would be a declspec involved. Unluckily I'm obviously missing something as even simplifiing as much as possible and points in between still not working.

Anyways as Tellie says you've built an RPM, it doesn't matter much.
Thanks for the RPM
