When I'm compiling my project, I've encountered the following compile error: undefined reference to symbol 'uregex_open_50'
/usr/lib64/libicui18n.so.50: error adding symbols：DSO missing from command line.
I add -licui18n -licuuc -licudata link flags in Makefile.am.
usemake -j32 -C src.
Then I use readeld -s /usr/lib64/libicui18n.so.50 | grep uregex_open_50,and find it.
Then I found that in urename.h file there is macro about function name substitution. #define uregex_open U_ICU_ENTRY_POINT_RENAME(uregex_open) U_ICU_ENTRY_POINT_RENAME(x) x ## _50. So the function name in the final project is replaced with a name with a _50 suffix.I want to know how to solve this problem.
