Problem with build

[dmitry-lipetsk]

Hello,

Could anyone help me build probackup?

I am trying to build it (Ubuntu 24.04) using your instruction.

PostrgreSQL was compiled with the following steps:

• meson setup build --prefix=/usr/local/pgsql --buildtype=debug -Dssl=openssl -Dcassert=true
• cd build
• ninja
• meson test
• sudo ninja install

Installed PG instance works as expected.

Build method 1 (PGXS)

Instruction:

To compile pg_probackup, you must have a PostgreSQL installation and raw source tree....

What is mean "raw source tree"? I pointed the folder with source that I used to build PG. Is it OK?

My command is:

make USE_PGXS=1 PG_CONFIG='/usr/local/pgsql/bin/pg_config' top_srcdir='/home/dima/.MY/GitHUB/Postgres/DEV20240722-work2/'

Errors:

/home/dima/.MY/GitHUB/PostgresPro/pg_probackup/work/src/utils/file.c:1581:(.text+0x3f74): undefined reference to deflateInit2_' /usr/bin/ld: /home/dima/.MY/GitHUB/PostgresPro/pg_probackup/work/src/utils/file.c:1601:(.text+0x4004): undefined reference to inflateInit2_'
/usr/bin/ld: /home/dima/.MY/GitHUB/PostgresPro/pg_probackup/work/src/utils/file.c:1630:(.text+0x40f3): undefined reference to gzdopen' /usr/bin/ld: /home/dima/.MY/GitHUB/PostgresPro/pg_probackup/work/src/utils/file.c:1633:(.text+0x410c): undefined reference to gzopen'
/usr/bin/ld: /home/dima/.MY/GitHUB/PostgresPro/pg_probackup/work/src/utils/file.c:1636:(.text+0x4133): undefined reference to `gzsetparams'
….

As I understand, a problem with zlib library. How can I fix it?

/sbin/ldconfig -p| grep libz.so says:

    libz.so.1 (libc6,x86-64) => /lib/x86_64-linux-gnu/libz.so.1
    libz.so.1 (libc6) => /lib/i386-linux-gnu/libz.so.1
    libz.so (libc6,x86-64) => /lib/x86_64-linux-gnu/libz.so

Build method 2 (build probackup in contrib folder of PG source tree)

Instruction:

The alternative way, without using the PGXS infrastructure, is to place pg_probackup source directory into contrib directory and build it there.

Ok.

I copyed the folder with source code of probackup in '/home/dima/.MY/GitHUB/Postgres/DEV20240722-work2/contrib/pg_probackup':

I opened a terminal in this folder and executed "make"

Error:

Makefile:48: ../../src/Makefile.global: No such file or directory
make: *** No rule to make target '../../src/Makefile.global'. Stop.

As I understand, the problem is here:

pg_probackup/Makefile

Lines 45 to 50 in a2510f5

	else
	subdir=contrib/pg_probackup
	top_builddir=../..
	include $(top_builddir)/src/Makefile.global
	include $(top_srcdir)/contrib/contrib-global.mk
	endif

Makefile.global was generated in "PG_SRC_TREE/build/src" not in "PG_SRC_TREE/src"

I corrected top_builddir with top_builddir=../../build but it did not help.

Error:

make -C ../../build/src/backend generated-headers
make[1]: Entering directory '/home/dima/.MY/GitHUB/Postgres/DEV20240722-work2/build/src/backend'
make[1]: *** No rule to make target 'generated-headers'. Stop.

make: *** [../../build/src/Makefile.global:384: submake-generated-headers] Error 2

What did I do wrong?

Thanks.

Hello,

I was able to find a temporary solution for this issue - I added PG_LDFLAGS = -lz in Makefile before including PGXS makefile.

ifdef USE_PGXS
PG_CONFIG = pg_config
# it is required for fixing a problem with zlib linking
PG_LDFLAGS = -lz
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)
else

I am not sure that it is right way, because -lz it is a specific option of GCC but this is working.

Could you proposal the true solution to this?

Thanks.

Is -dev package of zlib installed? I think it is zlib1g-dev or libz-dev.

[fukanchik]

"raw source tree" indeed is a postgres source tree. E.g. just postgres-dev package won't work. Below I am doing apt source postgresql-16 but your method of git cloning and building using meson should work also.

Here's dockerfile which builds ok on ubuntu 24.04.

FROM ubuntu:24.04
WORKDIR  /
RUN sed -i 's/^Types: deb$/Types: deb deb-src/' /etc/apt/sources.list.d/ubuntu.sources && apt update
RUN apt install -y dpkg-dev git make gcc gettext libkrb5-dev postgresql-server-dev-all vim
RUN apt install -y libssl-dev libz-dev libselinux-dev libxslt-dev libxml2-dev libreadline-dev libpam-dev
RUN apt install -y liblz4-dev libzstd-dev
RUN apt source postgresql-16
RUN GIT_SSH_COMMAND="ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no" git clone https://github.com/postgrespro/pg_probackup.git
WORKDIR /pg_probackup
RUN make USE_PGXS=1 PG_CONFIG=/usr/bin/pg_config top_srcdir=/postgresql-16-16.3 VERBOSE=1 clean install
```

Does this help?

[dmitry-lipetsk]

Is -dev package of zlib installed? I think it is zlib1g-dev or libz-dev.

Yes, I did it and got the following messages:

"raw source tree" indeed is a postgres source tree. E.g. just postgres-dev package won't work.

Ok, I did it.

My '/home/dima/.MY/GitHUB/Postgres/DEV20240722-work2' contains PG source tree (it was cloned from GitHub) and this tree was used to compile my installed PG instance.

Below I am doing apt source postgresql-16 but your method of git cloning and building using meson should work >also.

Here's dockerfile which builds ok on ubuntu 24.04.

...

Does this help?

I'll try to check it a bit later.

Thank you for your help.

[dmitry-lipetsk]

I tested PGXS method with PostgreSQL v16.3 (cloned from GitHub) and got the same problem with undefined references.

v16 was compiled with meson.

When I add PG_LDFLAGS = -lz - propbackup is built without any problems:

Here's dockerfile which builds ok on ubuntu 24.04.

Unfortunately, docker does not work on my ubuntu 24.04 (that works in VM / Hyper-V) - it crashes.

So, I can't check this scenario.

Ok, I have already been able to build probackup and it is enough to continue.

I hope this problem with build will be fixed in the future :)

I was able to reproduce your problem using the following dockerfile. Please note that even adding -Dzlib=enabled to the meson setup didn't help.

WORKDIR  /

Yeah, thanks for reporting. This have to be fixed.

An equal problem exists when Postgres was compiled with a support of LZ4 (?) library

I have not known how to fix it yet :(

UPD. PG_LDFLAGS = -lz -llz4
