Which ptxdist version are you using? At least for target packages we set it in the right place. For me it looks like this: [...] wrapper: /usr/bin/icecc arm-v7a-linux-gnueabihf-gcc -Wl,--as-needed -isystem [...]/platform-arm-hf/sysroot-target/include -isystem [...]/platform-arm-hf/sysroot-target/usr/include -O3 -D_LARGEFILE64_SOURCE=1 -DHAVE_HIDDEN -o minigzip minigzip.o -L. libz.a -L[...]/platform-arm-hf/sysroot-target/lib -L[...]/platform-arm-hf/sysroot-target/usr/lib -Wl,-rpath-link -Wl,[...]/platform-arm-hf/sysroot-target/lib -Wl,-rpath-link -Wl,[...]/platform-arm-hf/sysroot-target/usr/lib [...] The wrapper script adds it before the other options. > > If you start ptxdist with '-v' then all calls to the compiler and linker > > are logged.

The only thing that is added at the end of the command-line is PTXDIST_HOST_LDFLAGS and that's just the -L / -Wl,-rpath stuff. > And here is the missing BASH_VERSINFO of Apple's bash: > $ set | grep BASH_VERSINFO > BASH_VERSINFO=([0]="3" [1]="2" [2]="53" [3]="1" [4]="release" > [5]="x86_64-apple-darwin13") So we could check for the version.
