Can't build on Fedora 40 (GCC 14)

[acruise]

I realize Fedora is not a primary target, but people on other early-adopter distros like Arch are likely to hit the same issues. :)

This is after:

mkdir build; cd build; cmake ..

make -j10

Intel TBB

According to this similar issue this has been fixed upstream in TBB, but in the vendored version:

      |                    ^~~~

The workaround for this is to change line 225 of vendor/intel/tbb/src/tbb_src/include/tbb/task.h from:

        task* next_offloaded;

to:

        tbb::task* next_offloaded;

There are no FastPFOR includes in this file; I'm not sure where they're supposed to come from.

CURLOPT_PUT Deprecated

edit: Updating to https://github.com/aws/aws-sdk-cpp/commits/1.10.53 seems to avoid this error but I don't know if it's safe :sweat_smile:

My libcurl is version 8.6.0 and it complains that CURLOPT_PUT is deprecated and CURLOPT_UPLOAD should be used instead.

Indeed, changing line 414 of vendor/libawscpp-download/src/libawscpp-download/aws-cpp-sdk-core/source/http/curl/CurlHttpClient.cpp seems to help;

before:

                curl_easy_setopt(requestHandle, CURLOPT_PUT, 1L);

after:

                curl_easy_setopt(requestHandle, CURLOPT_UPLOAD, 1L);

Here are some workarounds to make the playground pass compilation, for commit d1c1d26.

• In tools/playground/playground.cpp, add header files:

  #include "headers/blockpacking.h"
  #include "headers/compositecodec.h"
  #include "headers/simdfastpfor.h"
  #include "headers/variablebyte.h"

• In line 17 of tools/playground/rle.cpp, instantiate CODECFactory first. Change line 17 to the following two lines:

  CODECFactory factory;
  IntegerCODEC &codec = *factory.getFromName("simdfastpfor256");

Here are some workarounds

Thanks, these definitely helped me reach a successful compilation. I'll make a PR for these changes if nobody beats me to it, but I can't easily check whether these changes will break other targets. :/
