Description

Hey, when trying to build on fresh Ubuntu 15.04 installation I got this problem:

I found the problem is in this command:

/bin/bash ../../ylwrap `test -f 'src/thriftl.ll' || echo './'`src/thriftl.ll .c thriftl.cc – /bin/bash /home/floyd/thrift/missing flex

Exactly in second argument to ylwrap which above is just string '.c'. The proper command to run should be:

floyd@floyd-VirtualBox:~/thrift$ cd compiler/cpp/
floyd@floyd-VirtualBox:~/thrift/compiler/cpp$ /bin/bash ../../ylwrap `test -f 'src/thriftl.ll' || echo './'`src/thriftl.ll lex.yy.c thriftl.cc – /bin/bash /home/floyd/thrift/missing flex

So instead of '.c' it should have 'lex.yy.c' name which is the default name for lex generated filenames AFAIK. After manually running this command the build continues and even finishes (hurray!).
