I’m trying to build cgx 2.19 from source on Mac OS.
I’ve tried following the Mac instructions from 2015 (noting that they apply to a different version of macOS). When I run
sudo make in the
/usr/local/CalculiX/cgx_2.19/src folder I get the following error:
parser.c:91:3: error: implicit declaration of function 'DrawCommandLine' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
DrawCommandLine(keystroke, strlen(keystroke) + *curshft);
It seems like the function definition for DrawCommandLine is not getting included. I’m not very familiar with C/C++ but it seems that this function is included in
cgx.c which itself is included by
Any ideas what’s going on?
in parser.c, change the first line:
in pickfunctions.c, correct line 4597:
correct the makefile:
-L/usr/lib -lGL -lGLU
-L/usr/X11R6/lib -lX11 -lXi -lXmu -lXext -lXt -lSM -lICE
Thanks for your reply. I’ve implemented the changes as you suggested, and the compilation does get a lot further. Now it seems to exit on the following error:
ld: library not found for -lSystem
collect2: error: ld returned 1 exit status
make: *** [cgx] Error 1
do you have XQuartz installed ?
Yes I do.
I think I’ve managed to get past the
ld error by including this in the
LFLAGS section in the makefile:
-L /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib \
It seems the compilation runs without errors, but ends with a lot of warnings like this:
ld: warning: object file (/var/tmp//ccrWCwNi.o) was built for newer macOS version (12.0) than being linked (10.17.4)
ld: warning: object file (/var/tmp//cck4ppOP.o) was built for newer macOS version (12.0) than being linked (10.17.4)
ld: warning: object file (/var/tmp//cc8xH23e.o) was built for newer macOS version (12.0) than being linked (10.17.4)
ok. I have this on my .bashrc:
on my Mac, after I open a .frd results file, I have to manually resize the cgx application window, for the model to show up. I first change its size to a small window then resize it to a normal one and the model shows up.
Thank you so much. It’s working now. I indeed need to resize the window down until I get the following warning:
GLUT: Warning in cgx: glutReshapeWindow: non-positive width or height not allowed
Then when I resize up, the model is viewable.
Thanks again, you’ve been incredibly helpful.
I had compiled it for macOS 10.13 some time ago but window was blank and I thought it didn’t work…thanks for the tip! Anyone knows what’s behind this behaviour?
