What did you expect to see?

Should build successfully

What did you see instead?

I initially got gcc not found error, so I installed TDM-GCC-64 and add path C:\TDM-GCC-64\bin, then, I got above error

Hi @zhangcicely !

I'm sorry I'm not an expert on Windows compilation but from your log it looks like you might have both cygwin (from the /cygdrive/ path you have in the log) as well as mingw (the compiler provided by TDM-GCC-64)
From looking at this stackoverflow thread, it looks like MinGW and Cygwin might not be playing well together especially for linking.
Would you mind checking if you can remove one or the other from the equation and try to recompile with only one ?

[zhangcicely]

Hi @Viq111

Thanks for replying, I removed cygwin, but I still got the same error, I think somewhere it is not cleaned. Just wonder if you may have seen similar issue before?
I removed MinGW also, but I ran into another issue. Another thread mentioned that cgo is not compatible with cgwin, and asked to use MinGW

Thanks,

zstd 1.41 build: Fix MinGW-W64 build by @myzhang1029 (#1600)

[Viq111]

Indeed facebook/zstd#1600
This seems to have been merged on April 25th.
The current included zstd version is 1.4.1: https://github.com/facebook/zstd/releases/tag/v1.4.1 which was released on July 19th so it should have this fix already
