[QUOTE=unconnected;535089]I've recently installed a newest version of prpserver and spent several hours figuring out why it could not connect to the database. Then I decided to search the forum and found this thread :smile:

Thanks to [B]amphoria[/B], his [URL="https://www.mersenneforum.org/showpost.php?p=349183&postcount=3"]advice[/URL] solved my problem.
Also, the applications did not compile with the error

[CODE]/usr/bin/ld: LengthCalculator.o: undefined reference to symbol 'floor@@GLIBC_2.2.5'
//usr/lib64/libm.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make: *** [prpserver] Error 1
[/CODE]until I added -lm option to the linker.

One more suggestion is to add prpadmin to the target all.
Does it worth adding these changes to the makefile?[/QUOTE]

Adding -lm yes, but I deliberately do not build prpadmin with "make all". I had my reasons at the time, but I forgot what they were. I can add it.
