Hi all,

I tried to follow the instruction to compile w64_qserver for R (http://code.kx.com/wsvn/code/cookbook\_code/r/w64\_qserver/?#aab6bb31e13bc2816b2db913b3fc5017c), but kept getting the following errors.

D:\Projects\KDB+\w64_qserver>gcc -c base.c -I. -I “C:/R/R-3.3.2/include” -D KXVER=3

In file included from base.c:16:0:

./k.h:88:0: warning: “isnan” redefined

 #define isnan _isnan

c.o: file not recognized: File format not recognized

I did the same for w32_qserver for R (http://code.kx.com/wsvn/code/cookbook\_code/r/w32\_qserver/?#adbc9418b31ab823417f1b088f9006e69) and it works fine.

I wonder whether c.o is indeed corrupted. Is there another place I can download c.o? Thanks a lot!

Hi George,

did you try this file, the 64bit version of c.o?

thanks

Thanks, Chris! Yes, I did. 
It turned out that c.o is fine, the problem was due to the compiler I used.

The new RTools has two versions of compiler for x64 and i386 respectively. 

I had to set my path to switch to the 64-bit compiler, which fixed the error.

Regards,

George
