Team, I tried on tags 0.13.0.4 0.13.0.5 0.13.0.6 0.14.1 tags and master branch.. All hit the same issue. Any idea about how to fix it? Thanks

@adrian-thurston Hi, could you guys please take a look? Thanks

adrian-thurston commented 3 years ago

Hi @bzhaoopenstack, I'll make a VM to investigate this. Shoot me a message if you have one already I can use.

adrian-thurston commented 3 years ago

Can't seem to find 7.6. I'll try with 7.8

adrian-thurston commented 3 years ago

Just realized I don't need centos for this. I had thought it was related to problems with the linking command. But I see now you're using -m a.out. Do you mean to pass -o a.out?

The -m arg is for generating C++ code that later gets linked into the target. Doing this requires writing some boilerplate yourself and preventing colm from compiling and linking the generated code. Normally I use -m with -c to say "please just compile the Colm code, I can compile and link the C code myself."

bzhaoopenstack commented 3 years ago

@adrian-thurston Thank you very much. I can repro on the Ubuntu 1804 too, for centos is just an example for this issue. ;-), sorry for making you inconvinent. a.out is a 'helloworld' sample exec file which compile by gcc.

So you suggest that we should use -m with -c in most cases, right?

bzhaoopenstack commented 3 years ago

And yes, I use -m with -c. It looks good from my side.

And yes, I use -m with -c. It looks good from my side.

without -m, generating c code,compile and link sucessfull,the result is: image

with -m generating for c++ code can not be link

image

with -m and -c，and than compile and link also occur the same error

adrian-thurston commented 3 years ago

You'll also have to use -p to generate the parser state tables and other boilerplate. Have a look at one of the src/host-* directories in the ragel repository. They link in two colm parsers into the same executable, rlparse and rlhc*. The rlparse parsers have reduction code associated with them. The rlhc parsers don't, just pure colm transform.

adrian-thurston commented 3 years ago

Closing as this appears to be wrong usage of arguments.
