Обсуждение: Need to install liblz4-dev
FYI, a few hours ago I started getting build errors on master due to
a missing liblz4 library error:
--> checking for liblz4... no
--> configure: error: Package requirements (liblz4) were not met:
--> Package 'liblz4', required by 'virtual:world', not found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LZ4_CFLAGS
and LZ4_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
make: *** [../../../src/Makefile.global:870: ../../../config.status] Error 1
However, I had /usr/lib/x86_64-linux-gnu/liblz4.so.1 installed on Debian
13. I had to install liblz4-dev ("dev") to allow the configure/compile
to succeed.

That's because of 7c1849311e49, hence my fault. You can also bypass
the failure by appending a --without-lz4 to your configure switches,
like one can do for ICU.

"Fault" seems the wrong word. This error is intentional. So you have to
go out of your way to build postgres in a way that cannot open
datadirs created by the default configuration.

My bigger point is that I didn't see any notification on hackers that
installing liblz4-dev would be necessary to continue compiling master.
I thought other hackers would want to know this.
