Search for a well known library.

Hello.

This is a general question.

I need to install a software from source.
During the configure command, I got an error :

checking for some_file... no
checking for SOMELIB - version >= 1.2.0... no
configure: error: a_software needs SOMELIB

But opensuse have installed SOMELIB6 which version is 1.6.0 which is >= 1.2.0
Generally speaking SOMELIB6 provides somelib.so.6 (somelib6.so.0) or which is not what the software is searching for.
Sometimes it is sufficient to make a link (somelib.so.6 → somelib.so or somelib6.so.0 → somelib.so.0 )

How to solve this kind of problem ?

I am looking for libgcrypt :


checking for libgcrypt-config... no
checking for LIBGCRYPT - version >= 1.2.0... no
configure: error: gnoMint needs libgcrypt

Any help is welcome

Hi
For the first one you may need to patch the Makefile to use pkgconfig to find things, far more reliable for cross distro building
https://people.freedesktop.org/~dbn/pkg-config-guide.html

For the second, use zypper (this is from Tumbleweed);


 zypper se --file-list libgcrypt-config
Loading repository data...
Reading installed packages...

S | Name                  | Summary                | Type   
--+-----------------------+------------------------+--------
  | libgcrypt-devel       | The GNU Crypto Library | package
  | libgcrypt-devel-32bit | The GNU Crypto Library | package

Note: For an extended search including not yet activated remote resources please use 'zypper
search-packages'.

First, realize that sometimes a library <package name> may have been renamed to something similar although not exact. Consider whether a slight name change in any way makes sense. Remember, a package name is just a name and may or may not be the same as its file contents, or the naming convention may be different from one system to the next (causing project problems when they build to different distros).

  1. Search your existing configured repos
zypper se* package_name *
  1. Search for a package that might provide the file
zypper se --provides* file_name*
  1. The “Cannot find” command
cnf *file_name*

  1. Use the online search tool at
    https://software.opensuselorg/search/

  2. Do an Internet search for the desired RPM package or file which might turn up in places like RPM PBone, RPMfind, etc

  3. Look up the project supporting the specific library to see whether it can be downloaded typically as a TAR file or compiled easily.

Always consider the source for whatever you install, whether you can trust its integrity and weight the risk you could damage your machine whether intentionally or not.

PS. And Malcolm points out that if you’re <building> something and not just installing a pre-built, then you may need the source headers for that package which will the package name with “-devel” appended when available.

HTH,
TSU

I have tried all libgcrypt i found from opensuse 10.1 up to leap 42.3

The probleme ( this is why I post this general question ) is that the installer search for a library but with a name that opensuse does not use.

I will try your suggested tips.

Thank you for helping.

Hi
As user tsu2 pointed out, it’s on OBS;
https://build.opensuse.org/package/show/home:ecsos/gnoMint

Ask the user to update to version 1.3.0;
http://gnomint.sourceforge.net/

Or branch, update and push to the user?

That does not really help.

1, 2, 3, 4, 5 does not help really because one don’t know the lib name or the file name “.so.” the installer is searching.
The generic name is libgcrypt
Opensuse use libgcrypt20 package ( which provide libgcrypt.so.20 ) (version 1.6.1) for opensuse leap 42.3
For Opensuse 10.1 the package is named libgcrypt and provide libgcrypt.so.20 version 1.2.4

For 6 OK, I will tried to add the -devel package

Thank you for helping

I am trying to compile version 1.3.0 from sourceforge.
I have put a bug request on sourceforge

I Have not found the package on opensuse certainly due to a bad search on google ( just to “download.opensuse.org” ).

I will try the package from : Welcome - openSUSE Build Service

Thank you for all your tips.

Hi

Hi

for a rpm build for you.

Hi
So, running the autogen.sh script will fix things up… Have a
test build on OBS;

Still need to fix the compile option flags…

Hi
And sorted, need to look at branching gnoMint and pushing the fix to allow cflags to be set and remove the -Werror (as per their ChangeLog)…

If you are building from source you need the DEV package for that library/

… and getting answers from yourself!!! :open_mouth:

WARNING: Try not to get into an argument.

Adding ECSOS repos I was able to install gnoMint.

I gave up its use because the level of aid was not sufficient in relation to my own knowledge of the domain.

For the same reason, after a try, I gave up the use of yast CA Management.

I have found a tutorial and writes a script to generate certificates from root ca cert, intermediate cert, up to server ca.
This is sufficient to make test locally.

Returning to my question “Search for a well known library”, next time i will try your suggestions as given at the beginning of this thread.

Thank you every body for trying to help me.
