Fail to execute example from the readme #1

Closed mingodad closed 2 years ago

Following the instructions on the readme I can build this project but then when try to execute the example from the readme (or any other sample) I'm getting this error:

make

[ 50%] Building CXX object CMakeFiles/culebra.dir/src/main.cc.o

./culebra ../samples/fizzbuzz.cul

@mingodad, thank you for the report. On my MacBook Pro, I get the following result. Could you give you more information about your environment?

~/culebra/build$ ./culebra ../samples/fizzbuzz.cul

The repl at first work but then:

./culebra
cul> puts(12)
Unknown error -1

I'm using the latest cloned repos for cpp-peglib/peglib.h and cpp-linenoise/linenoise.hpp symlinked on culebra/include.

@mingodad, I just tried it on Ubuntu 20.04 LTS, and the fizzbuzz worked with no problem.

I went through it with the debugger and found that it was failing on initialize_definition_ids and remembering a mention about needing to link against libpthread on cpp-peglib I added it and now it works.

Strange that it builds fine and silently fails to execute without -lpthread.
