Build fails on linux - Githubissues

Building TESS3 on ubuntu 16.04 I get the following error: x

Google suggests that the -lpthread flag is missing/in the wrong spot. Indeed, manually editing the build/CMakeFiles/TESS3.dir/link.txt file to gcc -lm -lpthread -g -O3 -Wall -Wextra CMakeFiles/TESS3.dir/tess3r/src/main/main_sNMF.c.o -o TESS3 -rdynamic libsNMFlib.a liblapack.a libcreateDataSetlib.a libcrossEntropylib.a libiolib.a libnnlsmlib.a libbituintlib.a libstatslib.a libmatrix lib.a libspatialRegularizationToolslib.a libFstlib.a liblapack.a libstatslib.a -lstdc++ -lm -lpthread allows the file to compile.
