C compiler cannot create executables when compiling OpenVPN

rob_xx17 · 03-24-2006, 03:16 PM

hey all.

I have SuSE 9.3 with OpenSSL 0.9.8a installed in /usr/local/ssl/bin/openssl. I have installed a number of programs, including OpenSSL, OpenSSH, rssh, and I never had any programs with the compiler. Now I'm trying to install OpenVPN 2.0.5. When I do ./configure I get an error message indicating that the program can't find my ssl. So I tried compiling with the following directive:

Code:

 ./configure --with-ssl-headers=/usr/local/ssl/bin/openssl

But, when I do that I get an error message:

Code:

configure: error: C compiler cannot create executables

What makes it stranger is that when I compile it without the --with-ssl-headers directive, the configuration goes through the part where it checks for gcc and c compiler. This is the code when I do a simple ./compile

Code:

checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes

and this is the code when I compile with the ./configure --with-ssl-headers=/usr/local/ssl/bin/openssl directive

Code:

checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.

Below is the portion of 'config.log' file pertaining to the error. I look through it but I didn't really find anything. I looked through the linuxquestions.org database but I didn't find anything similar to my problem. Could anyone help please? Thank you.

I am just guessing, but what do you have to point

Code:

 ./configure --with-ssl-headers=/usr/local/ssl/bin/openssl

? ssl execuables? or header?

rob_xx17 · 03-25-2006, 03:57 PM

that's the path to my executable. What is a header then and how do I find it? should I feel stupid

?

PDock · 03-25-2006, 06:32 PM

Yes. Header file is somename.h and normally in usr/include or /usr/local/include; perhaps a subdirectory.

find your openssl headers and change ./config command line accordingly.

rob_xx17 · 03-27-2006, 08:02 AM

here's where I'm at:

this is what I get when I type plain ./configure

Code:

checking for lzo1x_1_15_compress in -llzo2... yes
configure: checking for OpenSSL Crypto Library and Header files...
checking openssl/evp.h usability... no
checking openssl/evp.h presence... no
checking for openssl/evp.h... no
configure: error: OpenSSL Crypto headers not found.

so I go looking for the 'evp.h' file. I find it in the '/usr/local/ssl/include/openssl/' directory. So I recompile with this directory, as in:

Code:

./configure --with-ssl-headers=/usr/local/ssl/include/openssl/

I get the same error message. So I recompile like this:

Code:

./configure --with-ssl-headers=/usr/local/ssl/include/openssl/evp.h

and that's when I get this error message:

Code:

checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.

What do I do now? I'm quite clueless at this point. Thank you.

rob_xx17 · 03-27-2006, 08:22 AM

It looks like the compiler can't find 'evp.h' file even though it's right in the directory where it's looking. What does it mean and how do I go about it?

rob_xx17 · 03-27-2006, 08:47 AM

for those that follow up on threads, here's the solution:

Code:

./configure --with-ssl-lib=/usr/local/ssl/lib/ --with-ssl-headers=/usr/local/ssl/include/

I had to put explicitly two compile directives. Otherwise it didn't want to work. Strange, I guess.

Thanks Rob, this worked out for me, hadn't found the solution yet.

dude just

apt-get install build-essential

it will be ok
