 Posted: Fri Nov 02, 2018 5:10 pm Post subject: [SOLVED] libcurl.so.4: no version information available |
 |
|
Hi all,
I'm trying to get the VPN Unlimited application installed on my machine, but running the application results in the following errors:
| Code: |
# /usr/bin/vpn-unlimited-daemon
/usr/bin/vpn-unlimited-daemon: /usr/lib64/libcurl.so.4: no version information available (required by /usr/lib64/libvpnu_private_sdk.so.1)
/usr/bin/vpn-unlimited-daemon: symbol lookup error: /usr/lib64/libvpnu_private_sdk.so.1: undefined symbol: EVP_MD_CTX_new
|
Googling this error turns up a lot of results, and the cause is always that there are multiple curl installations on the machine. This PC only has one, installed normally through portage.
For background, I installed this application recently on a machine running Arch, for which there is an existing user-supplied package. It worked fine on that machine, so now I'm basically trying to follow along with that package build script to get it installed on Gentoo. Looking into the Arch package more in-depth, it is dependent on a curl installation that is built without versioned symbols. This appears to be done by configuring the curl build using the --disable-versioned-symbols flag. On the Gentoo machine, curl-config --configure does report that my curl was configured with this option, so it seems like it should be fine.
Also, if I peek into the libvpnu_private_sdk.so.1 library for which this is required, I can see that it needs libcurl.so.4:
| Code: |
# readelf -d /usr/lib/libvpnu_private_sdk.so.1 | head
Dynamic section at offset 0x1c8240 contains 34 entries:
Tag Type Name/Value
0x0000000000000001 (NEEDED) Shared library: [libcares.so.2]
0x0000000000000001 (NEEDED) Shared library: [libcurl.so.4]
...
|
And that library exists:
| Code: |
# ls -l /usr/lib/libcurl*
-rw-r--r-- 1 root root 1004322 Oct 31 20:42 /usr/lib/libcurl.a
lrwxrwxrwx 1 root root 16 Oct 31 20:42 /usr/lib/libcurl.so -> libcurl.so.4.5.0
lrwxrwxrwx 1 root root 16 Oct 31 20:42 /usr/lib/libcurl.so.4 -> libcurl.so.4.5.0
-rwxr-xr-x 1 root root 488224 Oct 31 20:42 /usr/lib/libcurl.so.4.5.0
|
I also noticed that the Arch package creates a bunch of additional symlinks by doing
| Code: |
for version in 3 4.0.0 4.1.0 4.2.0 4.3.0 4.4.0; do
ln -s libcurl-compat.so.4.5.0 "${pkgdir}"/usr/lib/libcurl.so.${version}
done
|
I created these links on my system as well, making it
| Code: |
# ls -l /usr/lib/libcurl*
-rw-r--r-- 1 root root 1004322 Oct 31 20:42 /usr/lib/libcurl.a
lrwxrwxrwx 1 root root 16 Oct 31 20:42 /usr/lib/libcurl.so -> libcurl.so.4.5.0
lrwxrwxrwx 1 root root 16 Nov 2 12:05 /usr/lib/libcurl.so.3 -> libcurl.so.4.5.0
lrwxrwxrwx 1 root root 16 Oct 31 20:42 /usr/lib/libcurl.so.4 -> libcurl.so.4.5.0
lrwxrwxrwx 1 root root 16 Nov 2 12:05 /usr/lib/libcurl.so.4.0.0 -> libcurl.so.4.5.0
lrwxrwxrwx 1 root root 16 Nov 2 12:05 /usr/lib/libcurl.so.4.1.0 -> libcurl.so.4.5.0
lrwxrwxrwx 1 root root 16 Nov 2 12:05 /usr/lib/libcurl.so.4.2.0 -> libcurl.so.4.5.0
lrwxrwxrwx 1 root root 16 Nov 2 12:05 /usr/lib/libcurl.so.4.3.0 -> libcurl.so.4.5.0
lrwxrwxrwx 1 root root 16 Nov 2 12:05 /usr/lib/libcurl.so.4.4.0 -> libcurl.so.4.5.0
-rwxr-xr-x 1 root root 488224 Oct 31 20:42 /usr/lib/libcurl.so.4.5.0
|
But I get the same error, so I removed those links.
Does anyone have any insight on what's going wrong here?

related to the openssl version, I think it needs 1.10 or greater for that

You have enabled curl_ssl_openssl use flag to curl? post emerge -pvq curl

Yes, curl_ssl_openssl is enabled:
| Code: |
$ emerge -pvq curl
[ebuild R ] net-misc/curl-7.62.0 USE="ipv6 ldap ssl static-libs threads -adns -brotli -http2 -idn -kerberos -metalink -rtmp -samba -ssh -test" ABI_X86="(64) -32 (-x32)" CURL_SSL="openssl -axtls -gnutls -libressl -mbedtls -nss (-winssl)"

I currently have 1.0.2p installed. If you don't mind, could you tell me a little more? How can you identify if an application needs 1.10 or greater? |

Good call. I'll see if I can make that work. If I can't, I'll post here again, if I can I'll mark this as solved. Until then, thank you both for the help, I appreciate it! |

| If you get it to work, please post the ebuild you use to install it. Such an ebuild may be useful to others, and would hopefully discourage people from copying the files into place by hand. |

Yes, I will definitely do that. This got me to the point where I can get the application to run, but there must be some other problem, because I can't get the VPN to connect. I'll open another thread to try to debug that, but for now, I'm marking this as solved.
As an aside, you don't need to use version 4.22. The download page for the application has separate downloads for Debian and Ubuntu, so 4.23 for Debian works. The Ubuntu ones seem to be linked against openssl 1.1.
Thanks for the help, everyone! |
