Hello,

thanks for tracking that down.  I have verified that the segfault issue also occurs when building on Ubuntu 16 x64.

Changing the command to: 
      ./configure_cmake.sh --prefix=/opt/snort --enable-tcmalloc --disable-docs
does not generate any errors and allows for successful build and installation.

however, running snort3 when -enable-tcmalloc is included as above generates a segfault;
   noah@snort18x:~/snort_src/snort3/build$ /opt/snort/bin/snort -V
   Segmentation fault (core dumped)

Please let me know if any further info is needed.
thanks
Noah

After looking at the errors, which I received too, the build fails at generating the text documentation at the target prefix. Using the --disable-text-docs alone did not stop the documentation generation. However, disabling all types of documentation generation resulted in a successful build.

./configure_cmake.sh --prefix=/usr/local/snort --enable-tcmalloc --disable-text-docs --disable-html-docs --disable-pdf-docs --disable-docs

This doesn't particularly answers your question, but hopefully can help you move along.

Thanks.

Interesting. Snort build 245 with tcmalloc over CetnOS 7 and FreeBSD 11 was successful. There have been recent changes in Ubuntu 18 that are making several apps too unhappy. I will do some testing on my side and report back if I come up with anything useful.

Hello,

when building Snort 3 245 with the --enable-tcmalloc flag, snort throws a segfault.

Environment: git clone of the latest Snort3 (b245) on Ubuntu 18 x64 in a VMware virtual Machine.

Commands:
cd ~/snort_src
cd ./snort3
./configure_cmake.sh --prefix=/usr/local  --enable-tcmalloc
cd build
make

Error:
...
Scanning dependencies of target all_built_sources
[ 97%] Documents: building commands.txt with 
Segmentation fault (core dumped)

When you remove the --enable-tcmalloc flag, snort compiles and runs without error:
