[users@httpd] Inquiry about apache httpd compile option

Hello,

First of all, thank you for reading this mail.

I send an email to this address to ask three questions about apache httpd compilation.

First, I am curious whether it is possible to know the compile option by only using httpd binary file.
I tried to compare the compile options between Bitnami and Drupal which are the containers using apache httpd server.
I could find the compile option of Bitnami from config.nice file in Bitnami's container.
However, I could not see any information of Drupal's compile option in Drupal's container.

So, I am curious whether it is possible to find the compile option of apache httpd by only using httpd binary file or apache2 binary file.

Second, does configure option(e.g., --enable-ssl --enable-so) which is used to build the apache httpd affect the httpd binary file?
I think that if the configure option is different, the httpd binary file is also different.
However, when I compiled the httpd program with two options (one command is "./configure" and the other is "./configure --enable-ssl --enable-so") and llvm, I could get the same bitcode files from two different options.

So, I am curious whether the configure option affects building apache httpd. If it does not affect, I also want to know whether apache httpd only uses same httpd binary file and supports some functions by only using configuration file (e.g, httpd.conf).

Lastly, may I know the compile option of httpd or apache2 which they can be installed using commands (e.g, apt install apache2)?

I am not sure whether asking these questions to this mail is right. If it is not right, may I know where should I ask about these questions?

I appreciate you for reading this email.

I look forward to hearing from you.

Sincerely,

What you need to understand is that httpd is quite modular and most
configure options (just run ./configure --help to see the available
options) will probably just impact the modules that end up being compiled
along with httpd.

So check the output of ./configure --help and test different options
according to your needs and test in a non system path (at least at first
until you get to know what you are doing), that is:

 ./configure --prefix=/home/your-user/httpd-test ......

Adding any module statically is an example, as is setting many flags
that shows up in `grep AC_DEFINE configure.in` to a non-default value,
such as --enable-v4-mapped or installation paths.
--enable-maintainer-mode is another example that drastically changes
compile flags.

I appreciate you for your response.

I understand that some ./configure flags can affect the httpd executable.

May I know some examples which ./configure flag affects the httpd executable?

It may, but a change to a ./configure flag will not necessarily affect
the httpd executable.

It may, but a change to a ./configure flag will not necessarily affect

I appreciate you for your response.

I compared two cases.( Apache httpd version is 2.4.56.)

A: httpd binary file created using command "./configure"

B: httpd binary file created using command "./configure --enable-ssl --enable-so"

I used the command "ldd httpd". However, I cannot find any difference in these cases.

I can check that these binaries use the same shared libraries.

Does apache httpd binary depend on the compile options?

Take a look at the ldd output instead.

I think some different build commands can make different binary files.

For example, I think that command "./configure" and command "./configure --enable-so --enable-ssl" can make each binary file which has different functionality.

However, when I see these binary files' bitcode files(e.g., httpd.bc), I can not find their difference.

So, I want to know whether apache httpd always supports same binary file(named httpd) regardless of compile options and whether configuration options of apache httpd are always determined by configuration files(e.g., httpd.conf).
