<solved> Compiling error -leay32 -lssleay32

darkp03

Hi!

Im trying to build an old project that was compiled using qt 4.4. Im currently running that version of Qt, with the latest qt creator.

Right now, if i try to compile I get the following error:

@
cannot find -leay32
cannot find -lssleay32
error: ld returned 1 exit status@

Theres a line in my Pro file that says

@
LIBS += $$LIBSDIR/iaxclient.dll $$LIBSDIR/sqlite3.dll $$CORELIBDIR/release/libkiax2core.a $$LIBSDIR/libjson.a $$LIBSDIR/libcurl-4.dll -leay32 -lssleay32
@

Thats actually the only part in my project where these files are mentioned. If i comment the -leay32 -lssleay32 part, i start getting thousands of "undefined reference to 'function name'" So that wont help.

Any idea how to solve this?
Thanks in advance!

Hi,

You need to add the path where these two libraries can be found. eay32 and ssleay32 are not standard libraries on windows. You have to install them with the correct OpenSSL package (meaning 32 or 64 bit) and then just:

@LIBS+= -LC:/OpenSSL-Win32/libs@

darkp03

Any guideline on which to install and how? There are thousands, and its not specified if its either 32 or 64 bits, or how to install them...

SGaist

Follow the link for windows "here":https://www.openssl.org/related/binaries.html

Wow, thanks for your help on that one!

So, i have managed to succesfully install openssl, I have checked on C:\OpenSSL-Win32\lib I have both libeay32.lib and ssleay32.lib. I have also added

@LIBS+= -LC:/OpenSSL-Win32/libs@

to my PRO file, but im still having the same errors... Do I have to manually copy the libraries and place them on the project directory? What am i missing?

SGaist

Are you building your application in 32 or 64 bit ?

darkp03

32 bit. What im trying to build, for a long time now, is the kiax2 softphone, which can be downloaded at this link

http://sourceforge.net/p/kiax/code/HEAD/tree/trunk/

I had to edit some parts, and install a 4.4 version of Qt in order for them to be compatible, and now im stuck with this error, the -leay32 -lssleay32

SGaist

Can you show your pro file ? What compiler are you using ?

Strange, it looks fine, did you check that the lib files can indeed be found in C:/OpenSSL-Win32/libs ?

Another thing, why are you trying to link against these libs ? They are not used directly by kiax2core

darkp03

First of all, I have to appologize, I just followed your instruction without paying a lot of atention, my bad. The folder

@
LIBS+= -LC:/OpenSSL-Win32/libs
@

doesnt exist, its actually

@
LIBS+= -LC:/OpenSSL-Win32/lib
@

Stupid mistake, but well, i should have realized.
Nevertheless, it still doesnt work (but im closer)

Now i Have only one error, instead of 2, I still have the "cannot find -leay32" (the lssleay32 was fixed!). I dont know exactly what library that one is. Im going to list everything looking "similar" that I can find on my OpenSSL-Win 32 folder.

On C:\OpenSSL-Win32 i have:
libeay32.dll
libssl32.dll
ssleay32.dll

On C:\OpenSSL-Win32\lib i have:
libeay32.lib
ssleay32.lib

On C:\OpenSSL-Win32\lib\MinGW I have:
libeay32.a
libeay32.def
ssleay32.a
ssleay32.def

On C:\OpenSSL-Win32\lib\VC and on C:\OpenSSL-Win32\lib\VC\static I have:
libeay32MD.lib
libeay32MDd.lib
libeay32MT.lib
libeay32MTd.lib
ssleay32MD.lib
ssleay32MDd.lib
ssleay32MT.lib
ssleay32MTd.lib

On C:\OpenSSL-Win32\exp I have:
libeay32.exp
ssleay32.exp

C:\OpenSSL-Win32\bin I have:
libeay32.dll
ssleay32.dll

bq. Another thing, why are you trying to link against these libs ? They are not used directly by kiax2core

Im sorry, but i dont understand exaclty what you are asking here. The project as it is, was downloaded from internet, If i comment or exclude anything on the line

@LIBS += $$LIBSDIR/iaxclient.dll $$LIBSDIR/sqlite3.dll $$CORELIBDIR/release/libkiax2core.a $$LIBSDIR/libjson.a $$LIBSDIR/libcurl-4.dll -leay32 -lssleay32@

It will start giving hundreds of errors of the type

@undefined reference to 'function name'@

Im sorry im not giving much information, I know how to program, but I suck when linking/compiling errors start to appear, when they dont refer to the code itself, but im always open to learning new stuff :D

SGaist

So since you are using MinGW use C:/OpenSSL-Win32/lib/MinGW

Don't worry, we're making progress ;)

darkp03

Wow! Thanks for this awesome support. Ive never expected that someone would spend so much time trying to help me. I really appreciate it!

Well, Ive managed to remove that error. Ive got 28 new ones, but as far as im concerned, they seem to be about something else.

I changed

@LIBS+= -LC:/OpenSSL-Win32/lib@

with

@LIBS+= -LC:/OpenSSL-Win32/lib/MinGW@

to include the MinGW libraries, and this brought an unexpected error, now, I have the "cannot find -lssleay32"
So, if I use the lib folder, im missing -leay32, if I use the MinGW folder, im missing -lssleay32, so my common sense thought "Lets include both!"

Ive managed to remove this error, now im having these missing functions

undefined reference to "json_tokener_parse"
undefined reference to "json_object_object_get"
undefined reference to "json_object_get_int"
undefined reference to "json_object_get_string"

and one last weird error (that I suspect has nothing to do with this issue) that says:

bq. ./release\Kiax2JSONBalance.o: bad reloc addres 0x5 in section '.text$_ZN13TiXmlDocumentD1EV[__ZN13TiXmlDocumentD1Ev]

But as I said before, this seems to be something completly different. Im going to google what this json crap is, lets hope I can get this up and running. Im marking this thread as solved, as the -leay32 -lssleay32 errors have finally disappeared

Thanks for being patient with me, really apreciate it!
