As I do not understand now much about RPM build, I'm trying to adjust the
existing .spec file, mixing stuff from Bill's port of courier-imap-1.5.3.
I also do not understand suficient about compiling/linking flags so I ask help
for the following seting I found in .spec x Bill's.spec
>From courier-dev:
%define configure CFLAGS="${CFLAGS:-%optflags}" ; export CFLAGS ;
CXXFLAGS="${CXXFLAGS:-%optflags}" ; export CXXFLAGS ;
FFLAGS="${FFLAGS:-%optflags}" ; export FFLAGS ;
./configure --host=%{_host} --build=%{_build} --target=%{_target_platform}
--program-prefix=%{?_program_prefix} --prefix=%{_prefix}
--exec-prefix=%{_exec_prefix} --bindir=%{_bindir} --sbindir=%{_sbindir}
--sysconfdir=%{_sysconfdir} --datadir=%{_datadir} --includedir=%{_includedir}
--libdir=%{_libdir} --libexecdir=%{_libexecdir}
--localstatedir=%{_localstatedir} --sharedstatedir=%{_sharedstatedir}
--mandir=%{_mandir} --infodir=%{_infodir}
>From Bill's port:
CFLAGS="%{l_cppflags} %{optflags}"; export CFLAGS
CXXFLAGS="%{l_cppflags} %{optflags}"; export CXXFLAGS
LDFLAGS="-L%{l_prefix}/lib"; export LDFLAGS
So first, are all %{l_xxx} OpenPKG stuff ? And if so, where are they
defined (by rpm perhaps?) ?
I do not understand the syntax like CXXFLAGS="${CXXFLAGS:-%optflags}"
Does this consider some default ? How to change this for OpenPKG ?
And as I'm testing and probaly making lots off errors, How do I tell rpm to just
build the binary from .src.rpm with installing it ?
Unfortunatly I do not have the time to learn all about rpm build (that would be
nice) and thats why I'm trying to adapt the existing .spec to get just
courier-imap build (The only package I realy miss in OpenPKG).
Thanks again for all help and tips
