I compile it whit the following:

nim -d:release --opt:size `-l:"-lpcre"` c osc.nim

When I execute the code on other machine:


# ./osc
could not load: libpcre.so(.3|.1|)
compile with -d:nimDebugDlOpen for more information

I can execute the code on my local machine.

libpcre.so missing on the other computers?.

zhouhaiming (orginal) [2019-09-02T06:13:37+02:00] view original

I want to compile static.

shashlick (orginal) [2019-09-02T06:14:42+02:00] view original

Also, you don't need the -lpcre cause using nre will automatically link to pcre. Also -l calls need to be passed in with the --passL flag.

PCRE gets dynamically linked by default. If you want static then check out nimpcre or use the -d:usePcreHeader with the -l flag.
