I'm packaging ginac for the Fedora Package Collection. Now I have the following rpmlint warning on ginac 1.4.4. Can you have a look at it and have it fixed for the next release, please?

[fab@laptop24 i386]$ rpmlint -i ginac* ginac.i386: W: shared-lib-calls-exit /usr/lib/libginac-1.4.so.0.0.4 exit@GLIBC_2.0 This library package calls exit() or _exit(), probably in a non-fork() context. Doing so from a library is strongly discouraged - when a library function calls exit(), it prevents the calling program from handling the error, reporting it to the user, closing files properly, and cleaning up any state that the program has. It is preferred for the library to return an actual error code and let the calling program decide how to handle the situation.

Perhaps the intention was to *return* something, and perhaps non-zero?

GiNaC itself doesn't call exit() or _exit(). What you're seeing is an artifact introduced into the library by flex. I suggest to ignore this warning for the time being. GiNaC-1.5 won't make use of flex any more in the library proper. Best -richy. -- Richard B. Kreckel <http://www.ginac.de/~kreckel/>
