[Gambas-devel] problems while installing gambas into a buildroot (needed for packaging)

You need to prefix your absolute install paths with a buildroot 
when building packages, because it's typically not done as root 
and therefore the user doesn't have access to install the files 
to their final destinations.  However, having packaged Gambas 
for almost a year now, I have simply replaced "make install" 
with the following in my specfiles:

export PATH=${RPM_BUILD_ROOT}/usr/bin:$PWD/src/comp:$PATH
install -d ${RPM_BUILD_ROOT}/usr/bin/
install -d ${RPM_BUILD_ROOT}/usr/share/doc/%{name}-%{version}
install -d ${RPM_BUILD_ROOT}/usr/include/
install -d ${RPM_BUILD_ROOT}/usr/include/%{name}
install -d ${RPM_BUILD_ROOT}%appdir/
install -d ${RPM_BUILD_ROOT}%appdir/lib/
install -s -m 0755 src/exec/gbx ${RPM_BUILD_ROOT}/usr/bin/
install -s -m 0755 src/comp/gba ${RPM_BUILD_ROOT}/usr/bin/
install -s -m 0755 src/comp/gbi ${RPM_BUILD_ROOT}/usr/bin/
install -s -m 0755 src/comp/gbc ${RPM_BUILD_ROOT}/usr/bin/
find src -name *.la -exec cp {} ${RPM_BUILD_ROOT}%appdir/lib \;
find src -name *.so* -exec cp -a {} ${RPM_BUILD_ROOT}%appdir/lib 
\;
cp -a src/share/gambas.h ${RPM_BUILD_ROOT}/usr/include/%{name}
find ${RPM_BUILD_ROOT} -size 0 -exec rm -f {} \;

My solution to this problem was adding the following to the 
install script:

tar cjvf ${RPM_BUILD_ROOT}%appdir/gambas-gui-%{version}.tar.bz2 
app/ `find src/ -name *.component`

and making gambas-gui a separate package dependent on gambas, 
gambas-lib, and gambas-help.  However, I also have a ln -s 
/usr/lib/gambas-(version)/bin/gbx-real /usr/bin/gbx

Granted that neither of these would be necessary if make install 
worked the "usual" way, but things are always tricky when you're 
writing part of an app in itself ;)
