32Kb limit building .dll files

[dmacias]

In Harbour for OS/2 development ( www.harbour-project.org ) we face from long time a problem using os2gcc compilers when we try to build some .dll files

Tracing I found an now famous 32 Kb limit:

---

Somewhere gcc is using 32 Kb limit for our case

gcc --> emxomfld.exe ( ld.exe )

( or is OS/2 limit ? :-) )

Yes, this is an OS/2 limitation. The usual workaround is to pass the arguments in a response file (emxomfld @filename.rsp). Without checking all the relevant code, I'm pretty sure that the compiler/linker driver (gcc) will not create a response file when invoking sub programs like as, ld or emxomfld. The easiest way to hack it into doing this would be to change pexecute() in libiberty/pexecute.c to create a response file for arguments exceeding, say, 24 KB. http://svn.netlabs.org/libc/browser/branches/libc-0.6/src/gcc/libiberty/pexecute.c#L803

mozilla is running into this as well: ​https://bug648134.bugzilla.mozilla.org/attachment.cgi?id=524988 (​https://bugzilla.mozilla.org/show_bug.cgi?id=648134).

This has been fixed in gcc 4.4.6.
