Compilation fails on Mac OSX High Sierra

[jstrube]

Steps to reproduce:

• download and extract LCIO-02-11
• cd LCIO-02-11
• mkdir build
• cd build
• cmake ..
• make

Result:

I've also been trying to compile with gcc-7 (homebrew version), but also without success.

• CC=gcc-7 CXX=g++-7 cmake ..

@jstrube I cannot reproduce your problem. I can build LCIO w/o problems on High Sierra. On my system /usr/include/sys/types.h exists. Are you sure your xcode and command line tools are installed correctly ? Concerning the gcc-7 build: Can you comment out the following lines:

IF( "${CMAKE_CXX_COMPILER_ID}" STREQUAL "GNU" )
 LIST( APPEND COMPILER_FLAGS -Wl,-no-undefined )
ENDIF()

in cmake/ilcsoft_default_cxx_flags.cmake and retry ? This is a fix recently reported for a Debian system - not sure it helps on MacOSX, though.

Also DD4hep compilations(cmake) fails

For @petricm's problem This line needs to be removed following #44 https://github.com/iLCSoft/LCIO/blob/master/cmake/LCIOConfig.cmake.in#L57

@gaede The XCode was indeed out of date. The OS update had not updated xcode. xcode-select --install indeed fixed it.

The gcc-7 fix results in cmake completing, but make results in

Homebrew update installed gcc-7.2.0.1 today. For whatever reason, that worked (with the lines commented out as suggested).
