Like for example the following case

/usr/bin/ld: /usr/local/lib/libjasper.a(jas_image.o): relocation R_X86_64_32 against `.bss' cannot be used when making a shared object; recompile with -fPIC
/usr/local/lib/libjasper.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make1: *** Error 1
make1: Leaving directory `src'
make: *** install-recursive Error 1


A jasper library that has been linked statically is trying to be linked into a dynamic Libraries linked to a dynamic library must use "relocatable" code, and normally static libraries aren't. Possible solutions are:

  • If possible, use a dynamic version of jasper. Build it with support for static libraries. Most rpm or deb packages already include a dynamic version that will be taken in preference. Or
  • Build jasper with the "-fPIC" CFLAG. In that case even the static library will be relocatable.
  • Disable shared libraries in ecCodes. In this case no dynamic library will be produced (just the static version) and the problem won't be applicable any more.
