Re: Linking a third party library with httpd during installation (Apache Users)

Thanks, @Eric, @Konstantin for pointing that out that missing quote and extra whitespace. Appreciate it. I'm new to all this linking and these always make me confused.

I tried the following,

CFLAGS='-DSSL_EXPERIMENTAL_ENGINE -DSSL_ENGINE -DOPENSSL_LOAD_CONF' LDFLAGS='-L./libxxx -Wl,-Bstatic -lxxx -Wl,-rpath=/opt/openssl/lib' ./configure --prefix=/etc/apache2 --enable-ssl --with-ssl=/opt/openssl/ --with-pcre=/usr/local/pcre --enable-so

and it shows me,

checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /bin/grep
checking for egrep... /bin/grep -E
checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu
checking target system type... x86_64-pc-linux-gnu
configure:
configure: Configuring Apache Portable Runtime library...
configure:
checking for APR... yes
setting CC to "gcc"
setting CPP to "gcc -E"
adding "-g" to CFLAGS
adding "-O2" to CFLAGS
adding "-pthread" to CFLAGS
setting CPPFLAGS to " -DLINUX -D_REENTRANT -D_GNU_SOURCE"
configure:
configure: Configuring Apache Portable Runtime Utility library...
configure:
checking for APR-util... yes
checking for gcc... gcc
checking whether the C compiler works... no
configure: error: in `/home/apache/Downloads/httpd-2.4.46':
configure: error: C compiler cannot create executables
See `config.log' for more details

I do not understand why it shows my C compiler is not working? The config.log https://pastebin.com/U72JMZqF

Thanks,

Shariful

Note that in your command line there is a whitespace just after
"LDFLAGS=" and before its supposed value.

A shell command may be preceded by a series of variable assignments.
When the shell encounters the whitespace just after "LDFLAGS=" it
interprets that it ends those assignments, and tries to execute
"-L./libxxx" as the command.
