I am buidling target websocket_app_ssl at Ubuntu 16.04. 

First I got two link errors not finding crypto and ssl libraries

I have these to at my computer:

/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 
/lib/x86_64-linux-gnu/libssl.so.1.0.0

Adding the first resolved the crypto but when adding the ssl library I got these errors:

C3/Cobj3.o: I funktionen ”inline_F81_1274”:
big_file_C3_c.c:(.text+0x229d5): odefinierad referens till ”OPENSSL_init_ssl”
C3/Cobj3.o: I funktionen ”F81_1273”:
(.text+0x26a60): odefinierad referens till ”OPENSSL_init_ssl”
C3/Cobj3.o: I funktionen ”F81_1275”:

C3/Cobj3.o: I funktionen ”F81_1276”:

C3/Cobj3.o: I funktionen ”F81_1277”:
(.text+0x2757e): odefinierad referens till ”OPENSSL_init_crypto”
collect2: error: ld returned 1 exit status


Which version of openssl  do I need? Have I used the wrong libraries?

I have this:

openssl version
OpenSSL 1.0.2g  1 Mar 2016

Check the Readme file about how to install it on Ubuntu.

Thanks

I used this readme file to solve the pproblem:


However, I installed version  1.1.0g as descibed in the readme file.

Hi

I got this linking problem back.It is the same computer and I have not done any large upgrades of it. Might be that some Ubuntu automatic updates has made it fail again. However, I started to go through the process in the readme file again but it fails when doing "make". I get this error:

/usr/bin/ld: test/sanitytest.o: relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a PIE object; recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status
Makefile.shared:179: recipe for target 'link_app.gnu' failed
make[2]: *** [link_app.gnu] Error 1
make[2]: Leaving directory '/home/anders/openssl-1.1.0g'
Makefile:8875: recipe for target 'test/sanitytest' failed
make[1]: *** [test/sanitytest] Error 2
make[1]: Leaving directory '/home/anders/openssl-1.1.0g'
Makefile:130: recipe for target 'all' failed
make: *** [all] Error 2

Any clue about this?

Regards

Anders

Some object modules have been compiled without the option -fPIC (or -fPIE). E.g., if `sanitytest` is an external module, compilation options could be checked for it.

(Alternatively, you can remove the linker option `-pie`, but it would make the resulting executable less relocatable.)

Hi

sanitytest is an external module. Nothing I have added. I have not changed anything, I just tried to re-make something that was building earlier, but of course things that openSSL depends on can have been updated.

Hi again

I executed "make clean" and was then able to build openSSL again and do the steps in the README file, but I still get the undefined references to "OPENSSL....."

Hi

I have gone through these steps in the readme-file (except I am using the "g" version. Do I need to do something more? I am not sure if any of the other steps in the readme-file is necessary to do at Ubuntu.

#How to use the latest OpenSSL 1.1.1a on Ubuntu
================================================

```bash
$>wget https://www.openssl.org/source/openssl-1.1.1a.tar.gz
$>tar xzvf openssl-1.1.1a.tar.gz
$>cd openssl-1.1.1a
$>./config -Wl,--enable-new-dtags,-rpath,`$(LIBRPATH)`
$>make
$>sudo make install

$>openssl version -a    

$>echo	If you have an already installed OpenSSL library remove it using

$>sudo apt-get remove libssl-dev
```

Rebuild the ldconfig cache using

```
$sudo ldconfig
```

Hi Anders, I've checked and everything looks good.
But now 18.04 provide the openssl package (https://packages.ubuntu.com/bionic/openssl)

So first check if you can find it
> apt-cache search libssl

Then, check if the package was installed

> tail /var/log/dpkg.log

Finally check the following and let me know what do you get?

>pkg-config --cflags openssl
>pkg-config --libs openssl
