#5982 closed bug (worksforme)

Incorrect dynamic library name in OSX

Reported by: r0ml Owned by: ekmett
Priority: normal Milestone:
Component: Compiler Version: 7.4.1
Keywords: Cc: pho@…
Operating System: MacOS X Architecture: x86_64 (amd64)
Type of failure: Runtime crash Test Case:

When building a simple program that is built using -dynamic, the resulting executable fails with the following error:


Referenced from: /usr/local/lib/ghc-7.4.1/libHSrts-ghc7.4.1.dylib Reason: image not found

[1] 90849 trace trap

The workaround in this case is to execute the following two commands:

otool -id /usr/local/lib/ghc-7.4.1/libffi.dylib /usr/local/lib/ghc-7.4.1/libffi.dylib

install_name_tool /usr/local/lib/ghc-7.4.1/libHSrts-ghc7.4.1.dylib -change /Users/ian/zz64/ghc-7.4.1/libffi/build/inst/lib/libffi.5.dylib /usr/local/lib/ghc-7.4.1/libffi.dylib

which is to say that the library at /usr/local/lib/ghc-7.4.1/libffi.dylib is identified as being /Users/ian/zz64/ghc-7.4.1/libffi/build/inst/lib/libffi.5.dylib which causes the linker to fail.

Dynamic linking has been much improved on OS X. But please re-open if there is still an issue.
