I've been trying to complie Audacity 2.2.1 for a couple of days now, and I keep getting this error.

Code: Select all
checking for library containing dlopen... no
configure: error: dlopen not found, required by Audacity


I've gone through and made sure that I have all the dependencies installed, and all of the "*-dev" versions of these dependencies, where available. I've made the /build directory in the audacity folder (~/audacity-minsrc-2.2.1-rc3), and I've run
Code: Select all
sudo ../configure CXXFLAGS=”-std=gnu++11″ --with-lib-preference="local system"
.

I've also run:
Code: Select all
sudo autoreconf --no-recursive -i
followed by
Code: Select all
sudo ../configure CXXFLAGS=”-std=gnu++11″ --with-lib-preference="local system"
, but I still get the same error. I've also tried running
Code: Select all
sudo ../configure CXXFLAGS=”-std=gnu++11″ --with-lib-preference="local system" --with-ffmpeg="system" --disable-dynamic-loading
I still get the same error; the full log is as follows:

I've tried downloading the source from the Audacity GitHub site and from Audacity's webside itself.

I'm a relative noob when it comes to Linux, so any help you can provide would be greatly appreciated.

Check if libltdl7 is installed.
I've never had to install that specifically, so I guess that it is usually pulled in as a dependency of something else. Did you install "build-essential"?

I did install build-essential. I also have libtdl7 and libtdl-dev installed.

FWIW, I had a previous version of Audacity installed--2.1.2 from the Ubuntu distro package. I uninstalled it with "sudo apt remove audacity" prior to trying to compile Audacity 2.2.1.

I use Xubuntu 16.04.
My procedure is like this post with just a few modifications: https://forum.audacityteam.org/viewtopi ... 33#p292433

Differences:

4. Configure Audacity:
Code: Select all
../configure --with-lib-preference="local system" --with-ffmpeg="system" --disable-dynamic-loading


5. Build audacity;
Code: Select all
make -j8

Note that I'm building on an 8 core i7. This tells "make" to run jobs on all 8 cores. If your processor has a different number of cores, change the number accordingly.
Without the "j" option, "make" will use a single core (and take much longer to build).

Before running step 6, if step 5 completes correctly, it should be possible to launch Audacity with:
Code: Select all
./audacity

Thank you! I had to re-download the source code (I kept getting an error during the make process), but that did the trick.

I don't think the OP's problem actually has anything to do with system configuration or installed libraries. The problem is that the "configure" command given on the "download source" page has been mangled to feature "smart" quotes. The Linux command line does not understand smart quotes, so if you copy-paste the command line from the website it will not work. The correct command is
Code: Select all
./configure CXXFLAGS="-std=gnu++11"

This looks the same at a casual glance but does not have the smart quotes and should be acceptable to your shell.

I'm posting here although the OP has now managed to build Audacity because this topic came up on a search for the error message. I've sent a report to the feedback address.

(It's quite a common, and very subtle and annoying, problem and not restricted to Linux; see this blog post by Raymond Chen for a more detailed discussion. Technically, the part of the command line that's got mangled determines the options passed to your C++ compiler. Since the configure script actually tests parts of your system configuration by compiling small C++ programs and checking for errors, a garbled command line that causes the compiler to break will fail the script as soon as it does, and it so happens that the "dlopen" check is the first such check it carries out. Hence the misleading error.)

That has now been fixed.

As a general guide, when compiling software, look in the source code for compilation instructions - those instructions are usually the most up to date.
In the case of Audacity, there are three relevant files, one for each supported platform:
* Windows: win\compile.txt
* macOS: mac/Build.txt
* GNU/Linux: INSTALL
