Hello,
I have built from source code the fpc-2.6.4 compiler on Linux.
I am not sure that I have correctly build it because:
1) It works well with my hello_world.pas code:
program Hello;
begin
writeln ('Hello, world.')
end.
$ fpc hello_world.pas
Free Pascal Compiler version 2.6.4 [2014/05/03] for i386

Compiling hello_world.pas
Linking hello_world
/usr/bin/ld: warning: link.res contains output sections; did you forget -T?
4 lines compiled, 0.3 sec
$ ./hello_world
Hello, world.
2) It does not work with my glut.pas code:
procedure glutInitPascal(ParseCmdLine: Boolean);
var
Cmd: array of PChar;
CmdCount, I: Integer;
begin
if ParseCmdLine then
CmdCount := ParamCount + 1
else
CmdCount := 1;
SetLength(Cmd, CmdCount);
for I := 0 to CmdCount - 1 do
Cmd[I] := PChar(ParamStr(I));
glutInit(@CmdCount, @Cmd);
end;
$ fpc glut.pas

glut.pas(15) Fatal: Syntax error, "BEGIN" expected but "end of file" found
Fatal: Compilation aborted
Error: /usr/bin/ppc386 returned an error exitcode (normal if you did not
specify a source file to be compiled)
3) It does not work when I am compiling hedgewars-src-0.9.20:
$ cmake . -DNOSERVER=1
$ make
[...]
[ 6%] Building Pascal object hedgewars/CMakeFiles/hwengine.dir/hwengine.o
options.inc(25,3) Fatal: Can't find unit GL used by uConsts

make[1]: *** [hedgewars/CMakeFiles/hwengine.dir/all] Error 2
make: *** [all] Error 2
It seems that my opengl unit is not found.
However, it seems to be installed because, as you can see, the files are here:
usr/lib/fpc/2.6.4/units/i386-linux/opengl/
usr/lib/fpc/2.6.4/units/i386-linux/opengl/freeglut.ppu

Do you know why I am unable to compile 2) and 3)?
Thank you.
Best regards.
