I have a problem in linking. I use gcc -c *.c *.cc = to compile=20 my source code(one c file, and other c++ files).

Then I use gxx -o test.exe *.o to link. There = is a=20 linking error:

= TDT3_I_10.o(.text+0x1195):TDT3_I_10.cc:=20 undefined reference to 'mytag(FILE*,FILE*)'

mytag(FILE*,FILE*)is in mytagf.c and I link mytagf.o = with=20 other .o files from .cc files (that is , except mytagf.c ,all other = files are=20 written in c++)

I use nm to see the content of my mytagf.o, then I=20 get:

It seems that there is the function = mytag(FILE*,FILE*). Why=20 can't my c++ obj file see the c obj file? Can I link c++ and c files = into a .exe=20 files?

Is there any environmental setup I haven't = done?

My environ.lst is as follow:

TMP=3DC:\WINDOWS\TEMP
TEMP=3DC:\WINDOWS\TEMP
PROMPT=3D$p$g=

output of go32-v2 is as=20 follow:

go32/v2 version 2.0 built Aug 12 1996 = 22:27:23
Usage: go32=20 coff-image [args]
Rename this to go32.exe only if you need a go32 = that can=20 run v2 binaries as
well as v1 binaries (old makefiles). = Put ahead=20 of the old go32 in your PATH
but do not delete your old go32 - = leave it=20 in the PATH after this one.
Set GO32_V2_DEBUG=3Dy in the environment = to get=20 verbose output.
