I know this may be considered by some "unrelated" but I have this little problem. I am running on the DevC++ compiler now, and yesterday I finally tracked down the libJPEG release that actually works with it. I compiled, and my engine ran beautifully. So I commit this whole mess to the CVS, and then move to my laptop. I update it there, worked out a single problem, and it now runs on my laptop.
I move back to my PC, and update that. Now I get the following linker errors, and what's worse, undoing what I did on the laptop doesn't fix them...
[Linker error] undefined reference to `_imp___Z16jpeg_read_headerP22jpeg_decompress_stru cti'
[Linker error] undefined reference to `_imp___Z21jpeg_start_decompressP22jpeg_decompress _struct'
... basically all the jpeg library calls I used. When I nm the libjpeg, I get the appropriate functions...
d000075.o:
00000000 i .idata$4
00000000 i .idata$5
00000000 i .idata$6
00000000 i .idata$7
00000000 t .text
U __head_libjpeg_6_dll
00000000 I __imp__jpeg_read_header
00000000 I __nm__jpeg_read_header
00000000 T _jpeg_read_header
... and so forth.
I notice that the function in the lib is
__imp__jpeg_read_header
but the function the linker is asking for is
`_imp___Z16jpeg_read_headerP22jpeg_decompress_stru cti...
(the linker didn't type a long enough error message)
and I think this is the source of the problem. The killer is, it all worked last night. Anyways, anybody have a fix for this prob?
Thx in adv
