Re: [boost] How to set LDFLAGS in 1.66.0?

I'm not looking to find an external library, I'm trying to set the RUNPATH on the boost shared libraries

There's no need to use an external library. You just pass options to b2. Are you sure that you've tried my suggestion on previous reply?

Ordinarilly, one just adds LDFLAGS to the configure script with the -Wl,rpath ...

Using boost libraries does not prevent you to do so. One could either specify RPATH for your boost library files, application executable, or both. BTW, looking at your pasted output of ldd indicates that you've set your RPATH for wrong value, but that should not be boost specific; try googling without 'boost' keyword? 2018-03-09 9:59 GMT+09:00 Dean Anderson :

Thanks for the reply.

I'm not looking to find an external library, I'm trying to set the RUNPATH on the boost shared libraries. For example:

The path on libstdc++ is set by the ld, so it finds the right compiler runtime...

libboost_wave.so needs a RUNPATH to where its going to be installed.

Ordinarilly, one just adds LDFLAGS to the configure script with the -Wl,rpath ...

Make sure to escape $ and " appropriately for your CI scripts. Note that there are actually two types of flags, i.e. (1) the flag for your application executable (the RPATH) and (2) a flag for your build system's sanity check (e.g. the "checking if *whatever* works..." internal binary flag for ./configure)

p.s. Invoke command below to check whether the flags are set: objdump -p ./a.out|grep RPATH

I need to set an rpath on the shared libraries. Any ideas how to do that?

...

Alternatively, is there a fork of boost that use the gnu build system?

Thanks!
