macOS Please help change from Linux to Mac OS (makefile)

[kaltmond]

Hi, I'm a newbie in Mac programming, used to work on ubuntu. Below is a makefile which works in Ubuntu, but when i run it in Mac via terminal it gives error. Can anyone tell me where to change so that i can run it without problems?

Error code is: "ar : creating archive libbg.a
ranlib: warning for library: libbg.a the table of contents is empty (no object file members in the library define global symbols)"

Thanks in advance for any help!

Original Code for Ubuntu is here:

Not sure what the problem is, but here are some suggestions for troubleshooting.

First remove the redirection to /dev/null for the ar command, and look at the output that the -v option is giving you.

You might also consider using libtool instead of ar + ranlib.

 

[kaltmond]

Wenn remove the /dev/null, output is:

ranlib: warning for library: libbg.a the table of contents is empty (no object file members in the library define global symbols)

And i'm not sure what the -v Option is

> no object file members in the library define global symbols

Are your .o files empty?
Can you post one of your .cc files and one of your .h files?

 

[kaltmond]

Problem solved, i forgot that all the .o files are created in ubuntu. I recreate them again in OS and now the compile is done without errors.
Thanks for all the help and hints.
