Hi Yann, Thank you very much. That command works! Configuration script runs with no error so far. Much appreciated.

Re: [users@httpd] Linking a third party library with httpd during installation
Hi Eric, I believe the *config.log* file that the error is referring to is in *httpd-2.4.46*'s root directory. Here is full the config.log, https://pastebin.com/U72JMZqF. On lines 101-105, it shows that my static archive file is missing, 1. configure:5361: checking whether the C compiler works 2. configure:5383: gcc -DSSL_EXPERIMENTAL_ENGINE -DSSL_ENGINE -DOPENSSL_LOAD_CONF -g -O2 -pthread -DLINUX -D_REENTRANT -D_GNU_SOURCE -L./libxxx -Wl,-Bstatic -lxxx -Wl,-rpath=/opt/openssl/lib conftest.c >&5 3. /usr/bin/ld: cannot find -lxxx 4. /usr/bin/ld: cannot find -lgcc_s 5. /usr/bin/ld: cannot find -lgcc_s 6. collect2: error: ld returned 1 exit status 7. configure:5387: $? = 1 8. configure:5425: result: no 9. configure: failed program was Any Idea why is that?

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.

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. https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_09_01 Best regards, Konstantin Kolinko - To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org For additional commands, e-mail: users-h...@httpd.apache.org

[users@httpd] Linking a third party library with httpd during installation
Hello, I'm trying to install httpd-2.4.46 from the source. Usually, I use the following command to configure and it works fine, *~/Downloads/httpd-2.4.46$ *CFLAGS='-DSSL_EXPERIMENTAL_ENGINE -DSSL_ENGINE -DOPENSSL_LOAD_CONF' LDFLAGS=-Wl,-rpath=/opt/openssl/lib ./configure --prefix=/etc/apache2 --enable-ssl --with-ssl=/opt/openssl/ --with-pcre=/usr/local/pcre --enable-so Currently, I'm trying to link a third-party library while installing the httpd. using the following command, *~/Downloads/httpd-2.4.46$* 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 the following error, -bash: -L./libxxx: No such file or directory However, the "*libxxx* " directory presents in the same directory from where I'm running the above command. I'm not sure if this is the right approach to link a library. Any help on how can I link a library to "*httpd*" while installing it? Thanks, Shariful
