Concurrency issue when compiling with 16 cores (libethercat.la is not compiled but test build requiring it is started) #10

Open Minipada opened 5 years ago

Description

I encountered issue when building on a system with 16 cores. When reaching libethercat_wrapper folder, it sometimes fail. It seems compilation of a test requiring "libethercat_wrapper.la" is started while it has not yet been compiled. When continuing the build after this failure, it works properly. There's something wrong in the generated Makefile right now.

Steps to reproduce the issue:

  1. Have a system with 16 cores (it may require less though, I didn't test)
  2. ./bootstrap
  3. ./configure --enable-sii-assign --disable-8139too --enable-hrtimer --enable-cycles
  4. make -j 16 all

Possible Solution

One way to go around the problem is to make using make -j1, where in this case it does not happen.

Current Behavior:
