Problems installing MCC uldaq on a Mac

[ajw36]

I'm trying to install mccdaq/uldaq on an iMac (Intel) running Monterey (v 12.1). I've followed the instructions at https://github.com/mccdaq/uldaq. When I get to './configure && make' I get the following errors:

Making all in src CXXLD libuldaq.la /Library/Developer/CommandLineTools/usr/bin/ranlib: file: .libs/libuldaq.a(hid_linux.o) has no symbols /Library/Developer/CommandLineTools/usr/bin/ranlib: file: .libs/libuldaq.a(UlCtrConfig.o) has no symbols ranlib: object: .libs/libuldaq.a(CtrInfo.o) malformed object (unknown load command 1) make[2]: *** [libuldaq.la] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2

Ive been unable to resolve this by internet searches. Would be very grateful if anyone is able to help. Many thanks. Alex.

We had another customer with possibly the same problem. Here is how he was able to resolve it:

ran the following commands:

which gcc /opt/local/bin/gcc gcc --version gcc (MacPorts gcc6 6.5.0_5) 6.5.0

This indicated that the C compiler was tied to MacPorts, which apparently had not updated since I had updated my operating system. Following the steps listed here, I was able to update MacPorts and resource gcc to XCode by default. Running those same commands after a terminal restart now gave:

which gcc /usr/bin/gcc gcc --version Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1 Apple clang version 13.0.0 (clang-1300.0.29.30) Target: x86_64-apple-darwin20.6.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

This confirmed that the C compiler was being sourced from XCode. I then ran ./configure && make and was able to compile it successfully!

Please let me know if helped. Regards, Jeff

@ajw36 I'm looking for some closure here, Did this resolve your issue?

[ajw36]

Dear Jeff, Thanks for your reply and sorry for late response - holiday! I'm working on this now - not sure if the problem is the same. The first commands give: which gcc /usr/bin/gcc gcc --version Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/usr/include/c++/4.2.1 Apple clang version 13.0.0 (clang-1300.0.27.3) Target: x86_64-apple-darwin21.2.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin

In your previous post you say "Following steps listed here ...", and I wondered if there is meant to be a link?

Dear Jeff, Just to be clear: the problem I'm still having is knowing how to 'resource gcc to XCode by default' Many thanks, Alex

Hi Alex, I've asked around here, we are not sure why you are having that issue. One suggestion is that you uninstall XCode, then reinstall it from the app store.

I also found this link when I Googled 'how to resource gcc to XCode by default': https://stackoverflow.com/questions/61876572/set-the-default-gcc-to-xcode-command-line-tools
