Hi all,
I want to create an rpm for a java program that is not from me because
one of my program depend on it.
The problem I have is that I want to create an executable that call java
with the right classpath. Bascially I want :
java -classpath %{_javadir}/%{jarfile} -DLibrary-Path=\${TLAPATH}
tlc.TLC \$@
The problem is that I want my package to be relocatable. I create the
executable in the %install section with a cat command. The best way
might be to find the relative path from %{_bindir}/tlc to
%{_javadir}/%{jarfile} but how can I do this ?
So I found a solution maybe you can comment on...
In the install section I just create empty file in order the package to
register it.
%install
[...]
touch $RPM_BUILD_ROOT%{_bindir}/tlc
chmod a+x $RPM_BUILD_ROOT%{_bindir}/tlc
Then in the post section, I really create the content of the file by
using the RPM_INSTALL_PREFIX variable.
%post
[...]
cat > ${RPM_INSTALL_PREFIX}/bin/tlc <<EOD
#!/bin/sh
if (! \$?TLAPATH) then
export TLAPATH= ${RPM_INSTALL_PREFIX}/share/%{name}/StandardModules
endif
java -classpath ${RPM_INSTALL_PREFIX}/share/java/%{jarfile}
-DLibrary-Path=\${TLAPATH} tlc.TLC \$@
EOD
I can see two problem with that.
The first one is that I need to rely on the definition of my macro
%{bindir} to be %{_exec_prefix}/bin and %_exec_prefix to be %{_prefix}.
Or have I an automatic solution to known the relation between %{bindir}
and %{_prefix} (same for %{_datadir} and %{_javadir})?
The second one might happen if I want to sign the package. Wouldn't it
say that the file has been modified by puting such things in the post
section?
