Not standard libs) I get this ... unless you have the appropriate .h files of course this is dangerous.. ther eare teh following things to consider.. 1/ does teh flag for 'readonly' in solaris map to the flag 'truncate on open' in a freebsd system call? (an example of what might happen) also what about structure padding considerations? how about the NUMBER of arguments.. symbols don't give this info.. FreeBSD lseek takes a 64 bit offset.. does solaris's? etc etc. same problems with linux.. it may link but..... why not compile on solaris and just use the solaris emulation? > > > /usr/libexec/elf/ld: section .stab.exclstr [00000000 -> 0000002e] overlaps > secti > on .stab.excl [00000000 -> 0000005f] > /usr/libexec/elf/ld: section .stab.index [00000000 -> 0000011f] overlaps > section > .stab.excl [00000000 -> 0000005f] > /usr/libexec/elf/ld: section .stab.indexstr [00000000 -> 000000fd] overlaps > sect > ion .stab.excl [00000000 -> 0000005f] > /usr/libexec/elf/ld: ck: Not enough room for program headers (allocated 6, > need > 7) > /usr/libexec/elf/ld: final link failed: Bad value > *** Error code 1 > > I'm not sure what this means exactly.
