[Bug 65602] New: Failed linking C shared library mod_md.so
https://bz.apache.org/bugzilla/show_bug.cgi?id=65602
Bug ID: 65602
Summary: Failed linking C shared library mod_md.so
Product: Apache httpd-2
Version: 2.4.49
Hardware: PC
Status: NEW
Severity: blocker
Priority: P2
Component: Build
Assignee: bugs@httpd.apache.org
Reporter: baobaoxich@gmail.com
Target Milestone: ---
This bug comes from at least version 2.4.48, but to the current version is
still not fixed.
Before compiling Apache httpd-2, I have successfully compiled (also compile
order) before using CMAKE (3.21.3): zlib (1.2.11), PCRE (8.45), Expat ( 2.4.1),
OpenSSL (1.1.1l), libxml2 (2.9.12), jansson (2.14), Brotli (1.0.9), Lua
(5.4.3), APR (1.7.0), APR-Util (1.6) .1), Nghttp2 (1.45.1), cURL (7.79.1).
With cURL, I compiled both dynamic libraries (before) and static libraries
(after).
But when comes to Apache httpd-2 compile:

Another thing you might try:
Make a local cmake project of your own, some simple hello world thing that
links libcurl. See if you can get that working on your system.
Then we can analyse the differences in your CMakeLists.txt and the one in
Apache.

Hello, I tried to create a topic according to your instructions on Apache
Lounge. Topic link here: https://www.apachelounge.com/viewtopic.php?p=41211
First, I don't know the syntax used in CMake, so I will use the syntax in Java
to explain.
The cause of the error is due to the CURL_INCLUDE_DIR and CURL_LIBRARIES
variables in CMakeLists.txt file which are declared but not have been
initialized. That is why CMake has not been able to find the directory and
library file of cURL (Unless you manually indicate the path by
-DCURL_INCLUDE_DIR and -DCURL_LIBRARY like the way of nono303).
I tried to change a bit, namely the value SET for CURL_INCLUDE_DIR and
CURL_LIBRARIES variables inside the CMakeLists.txt file (please see the
difference between the default version and the version I changed here:
https://www.diffchecker.com/Jre9F4Gr). And praiseworthy, it found cURL and
conducted normal compilation!
Anyway, I hope you can update this change to fix the problem with cURL in the
next versions.

Something is fishy.
What does the file '/phpStudy/Apache/lib/cmake/CURL/CURLConfig.cmake' contain?

In the call to 'link.exe' I see all libraries except libcurl. Does this somehow
not get picked up by cmake correctly? I am unware of any changes.

The latest version (2.4.52) has not fixed this error yet, I tried to build on
this version, it (seemingly) has not detected the curl path.

--- Comment #8 from Stefan Eissing <ic...@apache.org> ---
I am not a cmake export, but if you look at your logs, you see that '
jansson.lib' is appearing, but there is no 'curl.lib' anywhere to be seen.
If the linking is called without any curl.lib, it will fail obviously as you
describe with missing curl symbols.
Looking at CMakeList.txt, the linking of mod_md is defined with
SET(mod_md_extra_libs ${OPENSSL_LIBRARIES} ${CURL_LIBRARIES}
${JANSSON_LIBRARIES} mod_watchdog)
so it seems that the Cmake variable $CURL_LIBRARIES is empty on your system.
As you mentioned, you seem to get this somewhat working by adding libcurl
*explicitly*:
#470 SET(mod_md_extra_libs ${OPENSSL_LIBRARIES}
${CURL_LIBRARIES} ${JANSSON_LIBRARIES} mod_watchdog libcurl)
...
Which means that you curl cmake setup is somehow wrong. This looks like a
problem on your system. It does not look like a bug in the Apache httpd
software.
If stackoverflow is not helpful, maybe you can find other cmake users on
https://www.apachelounge.com

Hello, I tried compiling the latest version (2.4.57), but this error still
occurs.
As I reported earlier, the cURL variables in the "CMakeLists.txt" file were
declared but not assigned values, which led to this bug.
I've made some changes to the "CMakeLists.txt" file that automatically finds
and assigns values to cURL variables to resolve compilation errors related to
this bug (without having to recompile cURL again during HTTPd compilation).
Here is the link to the file "CMakeLists.txt" after I edited and successfully
fixed this bug: https://pastebin.com/kCTmeUyv
I also created a pull request on GitHub, if you're a maintainer, can you test
and merge it? Link to pull request: https://github.com/apache/httpd/pull/356
Thank you.

Well, I asked create a question about this on StackOverflow, no in-depth
solution was given. But there is a solution like this:
At line #46 of the CMakeLists.txt file add:
...
#46 add_subdirectory(srclib/curl)
...
At line #470 of the CMakeLists.txt file add "libcurl":
...
#470 SET(mod_md_extra_libs ${OPENSSL_LIBRARIES}
${CURL_LIBRARIES} ${JANSSON_LIBRARIES} mod_watchdog libcurl)
...
However, as noted above, this is not a good solution because doing so cURL will
be rebuilt again (even though it has been compiled twice before) during HTTPD
compilation.

The "bin" directory is a directory I created for convenience during
compilation. I've tried compiling directly at the root of the source code
(instead of compiling into the "bin" directory) but that didn't fix anything
either.

I don't know why, I'll upload my compiled command line. When compiling to
Apache HTTPD, even though the command prompt shows the path to cURL has been

And the compiler still got the error and stopped at [ 40%] Linking C shared
library mod_md.so.
Here is my compile command line:
https://drive.google.com/file/d/1suH_SJOTcw-t7tdqd7jt2Scxa5G8SxNX/view?usp=sharing
I tried comparing 2 CMakeLists.txt files of 2 versions 2.4.46 and 2.4.49:
https://www.diffchecker.com/FQiaZzbr
There is a slight change in SET(mod_md_extra_sources and SET(LIBHTTPD_SOURCES
in both CMakeLists.txt files of Apache HTTPD source code.
Before compiling, I also uncommented right after the "getting duplicate
manifest error with ApacheMonitor" line in the CMakeLists.txt file (after line
901) of the Apache HTTPD source code.
I remember one thing: In version 2.4.46 there seems to also be an error during
compilation but I don't remember in which module, the fix is to replace
SET(mod_md_requires OPENSSL_FOUND CURL_FOUND JANSSON_FOUND) to
SET(mod_md_requires CURL_FOUND) ) in the CMakeLists.txt file (remove
OPENSSL_FOUND and JANSSON_FOUND) but this seems to have stopped working from
version 2.4.48!
