RE: How do I resolve ncurses build error in source file generated by MKlib_gen.sh

[Peter Groves]

HI Thomas

Thank you so much for your prompt response. Much appreciated.

I should just mention that my build is on a VMWare Workstation 16 Player. The 
host version of awk is GNU Awk 5.0.1, API: 2.0 (GNU MPFR 4.0.2, GNU MP 6.2.0).
I've included three logfiles, 
- the first showing just the ncurses 5.3 package build error i.e. with 
"--disable-client" set in bluez-5.65.spec 
- the second with "--disable-client" removed, such that the logfile will also 
show the linker error for the bluez package build. 
- the third with ncurses package 6.5 (using 5.3 spec file to begin with) - for 
some reason the "--with-build-cc=gcc" setting that worked for 5.3 doesn't seem 
to work in this instance. Looking at 
https://invisible-island.net/ncurses/ncurses.faq.html#where_patches, it doesn't 
seem as 6.5 requires any patches.

        checking if the build-compiler "gcc" works... no

        Use --with-build-cc to specify the native compiler.
        error: Bad exit status from

Package extraction is not shown, as this would have occurred in earlier logs. I 
hope this will assist with regard to the ncurses build error.
Yes, the ncurses package is very old and would prefer to use a later version of 
ncurses if I had more confidence in generating an appropriate spec file. 

Kind Regards.
Peter

ncurses 5.3 is more than 20 years old.

Actually in a quick check, I can compile it on this (Debian/oldstable) machine. 
 Some versions of gcc won't do that -- but that would be reflected in other 
parts of the build.

The spec file (better, a pointer to where it can be inspected) would help to 
see if that's needed.

no - ncurses/tinfo/MKcaptab.sh - which uses awk.

The generated source should have those names.  Perhaps your build machine 
doesn't have awk (though that seems unlikely).  Attaching what I built just now 
for that, and lib_gen.c

If I had the complete build logs, I might see the problem.
I prefer having a compressed tar file of the logs, as an attachment.
