Solved: Re: ydk-cpp installation: Error building YDK

Ericzhou0000 · ‎12-12-2018

Hello, I was trying to install ydk-cpp on my mac(OS 10.14.2) and got a problem. I had already installed Pcre by brew install pcre but it reports fatal error: 'pcre.h' file not found. I have followed all the steps successfully on https://github.com/CiscoDevNet/ydk-cpp until Building YDK. Can anyone help me?

Here is the record:

Hi Eric
Something is wrong with your PCRE installation. Check 'pcre.h' file permission and ownership. Make sure there are no conflicts. Maybe try to build test program just to include the pcre.h.
I am sure this is not YDK issue.

Hi Eric

Could you please verify PCRE installation on your Mac.

On my Mac VM it is located here:

Yans-iMac:build yangorelik$ locate pcre.h

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/php/ext/pcre/php_pcre.h

/usr/include/php/ext/pcre/php_pcre.h

/usr/local/Cellar/pcre/8.42/include/pcre.h

/usr/local/Cellar/pcre/8.42/share/doc/pcre/html/pcre.html

/usr/local/include/pcre.h

Yans-iMac:build yangorelik$ ls -l /usr/local/include/pcre.h

lrwxr-xr-x 1 yangorelik admin 34 Oct 9 15:21 /usr/local/include/pcre.h -> ../Cellar/pcre/8.42/include/pcre.h?

?Hopefully you can fix this.

Regards,
Yan

Ericzhou0000 · ‎12-13-2018

I tried to build a test program in C which just includes pcre.h #include <pcre.h> in the same position as parser.h, which reported the error above, and it can be compiled. I cannot understand why there are in the same position but one reports error but the other not.

Same issue here. How did you solve this?
