Hi All,


There is a new version for rng-tools so I thought I would do an update but it=
 kept stopping saying that it required libcap and could not find it.

I noted that the libcap libs are in /lib and not in /usr/lib as the other pac=
kages that rng-tools looks for have their libs. (openssl, libxml2, curl, jans=
son)

The new version has a flag for the ./configure called libcap_LIBS which can b=
e used to override pkg-config.

I tried that in various ways such as libcap_LIBS=3D"/lib" or libcap_LIBS=3D"/=
lib/libcap.so.2.67" and others, but none of them worked. The ./configure stil=
l ended up with the message

checking for libcap... no
configure: error: libcap is required

I then noticed that libcap.pc is in /lib/pkgconfig/ while all the other packa=
ges being searched for are in /usr/lib/pkgconfig/

I then manually did a copy of libcap.pc to /usr/lib/pkgconfig/ and then re ra=
n just the rng-tools build and it then successfully found libcap and complete=
d the build. So the problem is definitely to do withy the unusual location fo=
r the library files of libcap.


So the question I have is what is the best way to deal with this.

Should I add into the libcap lfs a line that copies the libcap.pc to /usr/lib=
/pkgconfig/ or

is can someone tell me what I am doing wrong with the libcap_LIBS flag for ./=
configure


Regards,

Adolf.
