ROOT compilation of macOS 10.14 Mojave fails in PCRE installation #47

Closed zoglauer closed 5 years ago

zoglauer commented 5 years ago

Problem: The compilation of ROOT fails with this error message:

CMake Error at /Users/andreas/Science/Software/External/root_v6.14.04/root_v6.14.04-build/PCRE-prefix/src/PCRE-stamp/PCRE-configure-RelWithDebInfo.cmake:16 (message): Command failed: 1

'./configure' '--prefix' '/Users/andreas/Science/Software/External/root_v6.14.04/root_v6.14.04-build' '--with-pic' '--disable-shared' 'CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc' 'CFLAGS=-O'

make[2]: [PCRE-prefix/src/PCRE-stamp/PCRE-configure] Error 1 make[1]: [CMakeFiles/PCRE.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs....

And the PCRE configure file contains something like this:

configure: error: in /Users/andreas/Science/Software/External/root_v6.14.04/root_v6.14.04-build/PCRE-prefix/src/PCRE': configure: error: cannot run C compiled programs. If you meant to cross compile, use--host'. See `config.log' for more details

Solution: After installing XCode and the xcode command-line tools with xcode-select --install

Also install the package located at: /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14. pkg
