I have a problem in linking. I use gcc -c *.c *.cc to compile my source =
code(one c file, and other c++ files).
Then I use gxx -o test.exe *.o to link. There is a linking error:
TDT3_I_10.o(.text+0x1195):TDT3_I_10.cc: undefined reference to =
'mytag(FILE*,FILE*)'
mytag(FILE*,FILE*)is in mytagf.c and I link mytagf.o with other .o files =
from .cc files (that is , except mytagf.c ,all other files are written =
in c++)
I use nm to see the content of my mytagf.o, then I get:

It seems that there is the function mytag(FILE*,FILE*). Why can't my c++ =
obj file see the c obj file? Can I link c++ and c files into a .exe =
files?=20
What should I do?
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
winbootdir=3DC:\WINDOWS
COMSPEC=3DC:\WINDOWS\COMMAND.COM
DJGPP=3DC:\DJGPP\DJGPP.ENV
PATH=3DC:\DJGPP\BIN;C:\PROGRA~1\ULTRAEDT;C:\WINDOWS;C:\WINDOWS\COMMAND
windir=3DC:\WINDOWS
SNDSCAPE=3DC:\WINDOWS
BLASTER=3DA220 I7 D1 T2=20
CMDLINE=3Dgxx -o TDT.exe mytagf.o TDT3_I_10.o GetF_I.o Topic.o hash.o =
feature.o stoplist.o tools.o m-mtlib.a
output of go32-v2 is as follow:
go32/v2 version 2.0 built Aug 12 1996 22:27:23
Usage: go32 coff-image [args]
Rename this to go32.exe only if you need a go32 that can run v2 binaries =
as
well as v1 binaries (old makefiles). Put ahead of the old go32 in your =
PATH
but do not delete your old go32 - leave it in the PATH after this one.
Set GO32_V2_DEBUG=3Dy in the environment to get verbose output.
