Re: Compiling libssh for vxwork

["Zvi Vered" <veredz72@xxxxxxxxx>]

Hi Andreas,

Following is the output I'm getting now.
The first error is:
string begin index: 1 is out of range 0 - 0

Next is:
math cannot parse the expression: " * 16 + ": syntax error, unexpected

Then I'm getting:
Could NOT find ZLIB (missing: ZLIB_INCLUDE_DIR ZLIB_LIBRARY)
According to my knowledge, vxWorks tree does not contains ZLIB library.

Is it possible to compile libssh without ZLIB ?

Can you help solve those errors ?

In order to bypass the compiler check I added:
SET(CMAKE_PROJECT_NAME NONE)
at the top of the toolchain file.

Your help is highly appreciated.

Best regards,
Zvika

I guess you already built for VS9 in that directory, so you still have cmake
build files around ...

mkdir obj-vxworks
cd obj-vxworks
cmake -DCMAKE_TOOLCHAIN_FILE=path/to/toolchain.txt path/to/libssh
