 Description    

mkdir build
 
cd build
 
cmake .. -LAH
 
	...
 
	// creates libmysql* symbolic links
 
	CONC_WITH_MYSQLCOMPAT:BOOL=ON
 
	...
 
rm -f CMakeCache.txt
 
cmake .. -DCONC_WITH_MYSQLCOMPAT=1 ...
 
make -j4 V=1
 
rm -rf /usr/local/mariadb/
 
make install

note, NO SYMLINKS

ls -al /usr/local/mariadb/lib64/
 
	total 840K
 
	drwxrwxr-x+  2 root root 4.0K Apr  1 17:49 ./
 
	drwxrwxr-x+ 13 root root 4.0K Apr  1 17:47 ../
 
	-rw-r--r--+  1 root root 445K Apr  1 17:39 libmariadbclient.a
 
	lrwxrwxrwx   1 root root   15 Apr  1 17:47 libmariadb.so -> libmariadb.so.3*

	-rw-r--r--+  1 root root  22K Apr  1 17:39 libmysqlservices.a

checking sources

cd ../
 
rm -rf build
 
grep MYSQLCOMPAT `grep -rln MYSQLCOMPAT .`
 
	./cmake/mariadb_connector_c.cmake:SET(CONC_WITH_MYSQLCOMPAT ON)
 
	./libmariadb/CMakeLists.txt:FOREACH(V WITH_MYSQLCOMPAT WITH_MSI WITH_SIGNCODE WITH_RTC WITH_UNITTEST
 
??	./libmariadb/CMakeLists.txt:  ADD_OPTION(WITH_MYSQLCOMPAT "creates libmysql* symbolic links" ON)

trying instead

-	cmake .. -DCONC_WITH_MYSQLCOMPAT=1 ...
 
+	cmake .. -DWITH_MYSQLCOMPAT=1 ...
 
 
 
	make -j4 V=1
 
	rm -rf /usr/local/mariadb/
 
	make install

note, still NO SYMLINKS

I see 10.2.6 has been released. As configured above, installs from 10.2-branch still do not create the compat symlinks.

As that's changed behavior from earlier releases,

(1) is that the intention/plan going forward?
(2) should packagers accommodate locally?

Comment by Sergei Golubchik [ 2017-05-23 ]

A preliminary answer — no, this is not the intention, it's a bug that didn't make the deadline. Hopefully, it'll be fixed in the next release.

A proper bug resolution should come in a few of weeks, closer to the 10.2.7 release date.

fyi, then:

for those building/installing mariadb locally – 'above' a distro installed, earlier/different release of MDB – and your build's installed lib paths are modified at any point to precede distro-installed paths (e.g., /usr/local/lib64 preceding /usr/lib64), the presence of the distro's libmysqlclient.so – in the absence of these^ symlinks from your build – will be used by (the many) apps that (still) search for & link against libmysqlclient.so.

That can/will cause some ... interesting ... run-time issues.

For now, a DIY symlink is needed.
