Review Comment:
**UPDATED (Sept 2, 2024)**: @szaszm
I just double checked the **conanfile.py**, it appears zlibs is not in conan
package **shared_requires** tuple. I realized some other conan packages
depended on **zlib**, so conan automatically downloaded **zlib 1.3.1** prebuilt
conan package. I will add it explicitly, but with **zlib 1.2.11** for that
conan package version to match the version that standalone CMake would install
for MiNiFi. Here will be the updated **shared_requires** tuple
~~~bash
shared_requires = ("openssl/3.2.1", "libcurl/8.6.0", "civetweb/1.16",
"libxml2/2.12.6", "fmt/10.2.1", "spdlog/1.14.0", "catch2/3.5.4", "zlib/1.2.11",
"zstd/1.5.2")
~~~
I didn't see that missing header from zlib during compilation librdkafka
anymore when building MiNiFi with conan build. I also added in **zstd/1.5.2**
conan package to match standalone CMake's zstd version. I added this zstd conan
package because BundledRocksDB was complaining about not being able to find
**zstd::zstd**. So, for the conan build of MiNiFi, I added both zlib and zstd
to build MiNiFi successfully.
I will double check by manually building MiNiFi with conan and get back to
you, but for now, I updated the **conanfile.py** with **zlib** added to the
**shared_requires** tuple and its on the repo now @szaszm
When building MiNiFi with conan build, **217/219 ctests PASS**.
34 - ProvenanceTests (Subprocess aborted)
219 - ControllerTests (Failed)
I think **ProvenanceTests** from RocksDB fails because of
double free or corruption (!prev)
Test #34: ProvenanceTests ........ Subprocess aborted***Exception:
0.19 sec
In regards to this **ProvenanceTests**, the main difference between MiNiFi
conan build and standalone CMake build is that in conan build we use **zstd**
and **zlib** conan packages to try to link into CMake's system library
installed **RocksDB** while with standalone CMake approach, we use CMake to
**build and install zlib & zstd external system libs** while installing system
library **RocksDB**
@szaszm any thoughts on what could cause **ProvenanceTest** to have this
**double free or corruption (!prev)** error when building MiNiFi using conan?
This doesn't happen when I build MiNiFi with standalone CMake. Also in my much
larger PR where I added support to install **patched RocksDB conan package**
based on **standalone CMake's patched RocksDB**, I dont think I saw this ctest
error: https://github.com/apache/nifi-minifi-cpp/pull/1775
When building MiNiFi with standalone CMake, **all 275 ctests PASS.**
