build error: gcc-X.Y: No such file or directory

[apanqasem]

I am getting an error when I do make. It appears to be looking for a directory gcc-X.Y where X.Y is the gcc version number.

If I cmake without any arguments it looks for a directory gcc-4.9.
If I specify
cmake -DGPU_ARCH:STRING=50 -DGCC_CUDA_VERSION:STRING=gcc-7.4.0 ./
(gcc 7.4.0 is what I have in my system)
It complains about not finding gcc-7.4.0

Hava you solved this problem?

Change gcc-4.9 to gcc in CMakeLists.txt
SET(GCC_CUDA_VERSION "gcc" CHANE STRING " ...")
but i have got another error

gitsE' can not be used when making a shared object; recompile with -fPIC

我也是这样 您解决了吗啊

是没有安装NTL库的原因，cuHE需要NTL依赖，安装之后就没错了。NTL网站：https://libntl.org/doc/tour-gmp.html

请问下，我安装好了NTL的库，但是为什么仍然出现这个问题呢

解决了，是因为ntl编译的时候没有加上-fPIC，所以重新在ntl的makefile文件中-fPIC即可
