SQLite3 static for 3.44.2 and pthread compilation problem

@ab - I'm trying to upgrade SQLite3 in my mORMot1 application from 3.31.0 to 3.44.2 (to the latest static version uploaded to the mORMot repository), but I get various linking errors related to pthread and dlopen (sorry for big fragment) under x86_64-linux (win64 is OK)

I tried under Ubuntu 22.04 (GLIBC 2.35) and  Ubuntu 20.04 (GLIBC 2.31) with the same results..

I assume that you compile Linux static under newer OSes (newer libc) and this is the reason?

Re: SQLite3 static for 3.44.2 and pthread compilation problem

I'm confused a little, because the same sqlite3.o is used in mormot2.2_stable and TFB example compiles well. Any help is wellcome

Re: SQLite3 static for 3.44.2 and pthread compilation problem

I found this commit in sqlite3 build what replace all symbols pthread->_pthread + dl->_dl and issue #211
To solve my problem I do a backward replacement, and now linker is happy.
Linux script what do a replacing is here

Still do not understand why it compiles in mORMot2.

Re: SQLite3 static for 3.44.2 and pthread compilation problem

To solve a problem, described in #211 ( `GLIBC_2.34' not found ) I compile a production version of my product using docker with fpc what based on Ubuntu 20.04 (GLIBC 2.31)

Re: SQLite3 static for 3.44.2 and pthread compilation problem

Perhaps https://github.com/synopse/mORMot/commi … 237a1a138b
would fix the problem during our own static build.
When I run this script, now it compiles and links fine for both mORMot 1 and also mORMot 2.

I will release a new mORMot 1 + 2 static binaries soon.

Instead of a docker container, you can just use fpc-ootb binaries.
See https://github.com/synopse/mORMot2/blob … ild_fpc.sh

Re: SQLite3 static for 3.44.2 and pthread compilation problem

Thanks a lot! BTW new binaries can be released with SQLite3 3.45.1 (where JSON and read performance improvements are introduced)
