Re: Build 5-5-9 in cygwin

[philippe beaucart]

For the previous issue, I commented stdlib.h as follow, preventing the compile to stop after 4% progress :
// row 163: char * _EXFUN(dtoa,(double, int, int, int *, int*, char**));

Then compile still blocking at the linking stage :
[ 86%] Building CXX object sql/CMakeFiles/mysqld.dir/main.cc.o

make[2]: *** [sql/mysqld.exe] Error 1

make: *** [all] Error 2

Blocking configuration is :
CC=gcc; CFLAGS=-O3 ; CXX=gcc ; CXXFLAGS="-O3 -fno-exceptions"; export CC CFLAGS CXX CXXFLAGS
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DWITH_EMBEDDED_SERVER=0

Checked:
It looks like that __cxa_pure_virtual is in libstdc++.{a,so}
I checked that : libstdc++ and libstdc++6-devel are installed.


=> What are the right options to compile these mysql sources within cygwin or what shall I proceed ?

Thx in advance for support.
