Re: [yocto] ClamAV PCRE support
Hi Tom, I never tried to get clamav to run, but please see my comments below.

Even if you do get around this error by passing the path to configure, using binconfig files to evaluate paths has been disabled in OE-core layer. So, you will have to fix the configure/pcre.m4 file in clamav to do this using .pc file from libpcre instead. Sorry, I'm not clear on which file needs fixing? I can only find pcre.m4 at tmp/work/armv7a-neon-poky-linux-gnueabi/clamav/0.99.2-r0/git/m4/reorganization/libs/pcre.m4 Isn't this generated during build? I'm sorry I'm also not clear on what needs changing, where can I find the correct .pc file for libpcre? I guess Anuj has a much better understanding about ClamAv and friends, but in general: .pc files are for the pkg-config utility[1][2]. You might want to try to compile libpcre and clamav natively on your target board. From there I would try to "steal" the relevant information and feed it back into the recipe(s). [1] https://linux.die.net/man/1/pkg-config [2] https://en.wikipedia.org/wiki/Pkg-config Also I guess that the file you need to fix is: ./m4/reorganization/libs/pcre.m4 with the input of whatever libpcre has in the libpcre.pc... or so file.

Hi, Does anyone have any ideas for how I might fix this bitbake error? Also is there an example initscript to start clamd? Thanks in advance.

[yocto] ClamAV PCRE support
Hi, I am adding ClamAV to our custom image and have added the following to our main .bb file: IMAGE_INSTALL += " clamav clamav-daemon clamav-clamdscan" When I run clamscan on our board I get a number of errors of the form "logical signature for ... uses PCREs but support is disabled, skipping" so the solution would appear to be to add PCRE support. In the ClamAV bitbake recipe I see there is a PACKAGECONFIG variable for PCRE, so to test if this is the solution I have added the following to my local.conf: PACKAGECONFIG_append_pn-clamav = " pcre" and have also added " libpcre2" before "clamav" in the IMAGE_INSTALL as above. Unfortunately when I run bitbake I now get a configure error similar to the following: configure: error: cannot locate libpcre2 or libpcre at /tmp/work/armv7a-neon-poky-linux-gnueabi/clamav/0.99.3-r0/recipe-sysroot/usr/lib I have attempted to solve this by creating a .bbappend file in my layer containing the following to try and force it to build libpcre first DEPENDS += " libpcre2" however this has no effect on the error, I assume this may not be the way to solve the dependency problem.
