@waranlogesh I suppose you have multiple installations of libxmlsec1: one via apt, version 1.2.28 and one via linuxbrew, version 1.2.32. pkg-config shows flags for the lib version installed via apt, while the 1.2.32 installed into /home/linuxbrew/.linuxbrew/Cellar/libxmlsec1/ is used for building. Using the version installed via apt, the installation runs fine here:

$ docker run --rm -it ubuntu:20.04
# apt update && apt full-upgrade -y
# apt install libxml2-dev libxmlsec1-dev libxmlsec1-openssl python3-dev python3-pip python3-venv build-essential pkg-config

@hoefling Thanks for the response. I was able to install using libxmlsec1 from apt.

Is there any way we can have compatibility with the homebrew version?

[hoefling]

@waranlogesh I don't know how linuxbrew builds the libraries and honestly don't have time to look into it, but at least xmlsec1 build looks broken to me. To reproduce your error from above:

$ docker run --rm -it linuxbrew/brew:latest
# su linuxbrew
$ export PATH=/home/linuxbrew/.linuxbrew/bin:$PATH
$ brew update
$ brew install python gcc libxml2 libxmlsec1 pkg-config
$ gcc-11 $(pkg-config --cflags xmlsec1) $(pkg-config --libs xmlsec1) tst.c -o tst
tst.c: In function 'main':
tst.c:4:16: error: 'xmlSecTransformXsltId' undeclared (first use in this function); did you mean 'xmlSecTransformXPathId'?
    4 |   printf("%s", xmlSecTransformXsltId);
      |                ^~~~~~~~~~~~~~~~~~~~~
      |                xmlSecTransformXPathId
tst.c:4:16: note: each undeclared identifier is reported only once for each function it appears in

with tst.c being simply

#include <xmlsec/transforms.h>

int main() {
  printf("test: %p\n", xmlSecTransformXsltId);
  return 0;
}

This indicates xmlSecTransformXsltId is not available, thus it isn't possible to build the bindings. Most likely a misconfigured library build in the first place. This isn't the case if I build the lib in e.g. a fedora:rawhide container, using xmlsec1.spec with version number patched to 1.2.32. You can report the issue upstream if you wish; I will leave this issue open for now anyway.

[hoefling]

@waranlogesh after I got some sleep - actually it's because the libxmlsec1 is built without XSLT support, and xmlsec code doesn't distinct between both variants. I will add compile-time checks for XMLSEC_NO_XSLT and disable the relevant functionality. Good catch!

[waranlogesh]

Thank you @hoefling
