QNX_HOST environment variable not set #3163

Closed liujie316316 closed 2 years ago

liujie316316 commented 2 years ago

I am compiling mlpack using QNX.Keep reporting the following errors: CMake Error at CMakeLists.txt:28 (message):QNX_HOST environment variable not set!!! I have added the following to CMakeLists.txt: set (QNX_HOST “/data/QNX/qnx700/host/linux”) set (QNX_TARGET “/data/QNX/qnx700/target/qnx7”) But it still reports an error. Does anyone know what I should do ?

It looks like you have multiple issues. If you can isolate the problem better, it's a little bit easier to help. The updated version in the StackOverflow post you linked to suggests that you have Armadillo configured incorrectly. Make sure that armadillo_bits/config.hpp has its settings set correctly for whatever BLAS or LAPACK library you are using with Armadillo and mlpack. Specifically I suspect that ARMA_BLAS_UNDERSCORE needs to be set, but it may not be that simple.
