make error

[yoonkihoon]

Hi,
How can I get around with this make error?

2bwt-lib/Socket.c:90:20: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]
90 | if (socketPath == '\0' || socketPath[0] == '\0') {
| ~~~~~~~~~~~^~~~~~~
2bwt-lib/Socket.c: In function ‘Socket* SocketInitiateConnection(int, const char*)’:
2bwt-lib/Socket.c:152:20: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]
152 | if (socketPath == '\0' || socketPath[0] == '\0') {
| ~~~~~~~~~~~^~~~~~~
make: *** [: 2bwt-lib/Socket.o] Error 1

Thanks!

Could you state the version of g++ being used?

I had the same error

I did run in to the same error:

I hope to work with a NVIDIA GeForce RTX 2070, CUDA version: 11.6.

Did any one find a fix for this error?

Compare to NULL could fix these.
Try modify 2bwt-lib/Socket.c line 90 and 152 to if (socketPath == NULL || socketPath[0] == '\0') {.
