  • 1.  Perl 5.38.2 build from SRPM fails

    Posted 26 days ago

    Hi folks, 

    faced a strange bunch of errors during the make make depend phase of a perl 5.38.2 build (based on SRPM download from toolbox). Lpar is running AIX 7.2 with gcc10. So far I tried to reinstall gcc10 packages - but no success.  rpmbuild runs fine until the make depend phase :

    > rpmbuild -bb perl-5.38.2-1.spec

    make: *** [Makefile:255: generate_uudmap.o] Error 1

    Looking at the signal.h file in the in the include_fixed directory the definition of the siginfo_t structure is enclosed in a conditional ( #if _XOPEN_SOURCE_EXTENDED==1 ) that seems not to be set .. 

    Seting the _XOPEN_SOURCE_EXTENDED variable to 1 caused the makedepend to run successfully .. but lost of fails during the make phase (so maybe not the best option).

    Not really sure what the root cause is or what to try next ... so any ideas are welcome :-) 

    Thanks a lot, 

    Volker

    _ALL_SOURCE will usually set _XOPEN_SOURCE_EXTENDED. This is done in the /usr/include/standards.h file. Probably you can create the preprocessing file for the failing compilation command (by adding -E) and debug further.
