# Stripped down, w64devkit, static, unity build of the PCRE2 POSIX regex
|
|
# library. This script builds and installs regex.h and libregex.a inside
|
|
# w64devkit. Link with -lregex. It is pretty bulky, nearly 300KiB.
|
|
#
|
|
# Copy and run this script in the root fo the PCRE source tree. Tested
|
|
# with PCRE 10.43.
