Hi,
I don't know if I found the right group. If not, please redirect me to
the right group.
I just made my first C++/C combined project and it works on windows. Now
I want it to work on linux. So I have changed main.c to main.cpp and
also have a new C++-function in the file: output_energy.cpp. The rest
are C-functions.
How should the make-file be modified? I know that main must be processed
by a C++-compiler so I changed CC = gcc to CC = g++ in the makefile
below (it used to work, when my project was pure C)...
---
.c.o:
$(RM) $@
@ #
$(CC) -c $(CFLAGS) $(SRC)/$*.c
PGM = simulate
OBJ = \
main.o \
array_functions.o \
band_solve.o \
check_errors.o \
import_data.o \
memory_functions.o \
mesh_functions.o \
polymesh.o \
porosities.o \
read_materials.o \
result_output.o
CC = g++
MV = mv -f
CP = cp
RM = rm -f
PROTO_DEFINES = -DFUNCPROTO=15 -DNARROWPROTO
STD_DEFINES = -Dlinux -D__i386__ -D_POSIX_C_SOURCE=199309L

CFLAGS = $(PROTO_DEFINES) $(STD_DEFINES) -g -W -Wall -ansi

Make returns with Error 1 in one of my files. It says:
...
...
cc1plus: warning: command line option "-Wstrict-prototypes" is valid for
C/ObjC but not for C++
cc1plus: warning: command line option "-Wmissing-declarations" is valid
for C/ObjC but not for C++
cc1plus: warning: command line option "-Wnested-externs" is valid for
C/ObjC but not for C++
.//porosities.c: In function 'void p_factor_cell_results(double**, int,
int, double*, double*, double*, double*, double**, unsigned int)':
.//porosities.c:65: error: invalid conversion from 'void*' to 'tablevalues*'
make: *** [porosities.o] Error 1
What do I do? I think I need to tell my makefile that most of the files
should be compiled by a C-compiler (gcc?) and main.cpp and the other
.cpp files should be compiled with g++?
TIA...
Best regards
