#51726: Gildas Install Fail ------------------------+---------------------- Reporter: jtb1435@… | Owner: smaret@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: gildas | ------------------------+---------------------- Comment (by bardeau@…): Ok. So that's really a symbol issue. That's hard to debug without having access to an identical machine and reproducing the bug. I see several options, from easiest to more complicated: 1) Use the MacPorts compilers, i.e. sudo port select gcc mp-gcc5 This will change gcc and g++ from Apple LLVM ones to MacPorts ones. This can be a problem for other software if they were relying precisely on the Apple compilers. Note that this does not solve the issue, this circumvents it by using another configuration. Once the compilers are changed, you should rebuild gildas from scratch. 2) Update the Apple compilers. You have Apple LLVM version 5.1 (clang-503.0.38), but I have 6.1. Compilers can be updated by updating Xcode ( https://developer.apple.com/support/xcode/ ). However there is no guarantee this solves the issue. 3) Compile Gildas "by hand" (see http://www.iram.fr/~gildas/dist/gildas.README section IV.2). The bug won't disappear but we will will able to make some tests and iterate together.
