Re: A few Issues Building Snort++ (3.0.0-a4-b244) on Ubuntu

[Noah Dietrich <noah_dietrich () 86penny org>]

Thank you Russ and YM for your help

//------------------------------------------------------------------
1. SafeC issues:
I see the same results as YM, snort says during the install that safec
isn't avaliable, but ldd shows it included:

./configure_cmake.sh --prefix=/opt/snort
(...)
Feature options:
    Flatbuffers:    ON
    Hyperscan:      ON
    ICONV:          ON
    LZMA:           ON
    *SafeC:          OFF*
    UUID:           ON
(...)

noah@snort16x64:~/snort_src/snort3/build$ *ldd /opt/snort/bin/snort | grep
safe*
libsafec-1.0.so.1 => /usr/local/lib/libsafec-1.0.so.1 (0x00007f2e8d58b000)

I manually set the PKG_CONFIG_PATH before the ./configure_cmake.sh step
with no change in the results, neither of the below made any difference:
export PKG_CONFIG_PATH=/usr/local/include/libsafec/
export PKG_CONFIG_PATH=/usr/local/include/

This looks to be a minor bug, especially if SafeC support is actually
enabled.

//----------------------------------------------------------------------
2. Snort Extras throwing error on 'make' issue
this seems to work when using --prefix=/opt/snort, but not when using
--prefix=/

export PKG_CONFIG_PATH=/opt/snort/lib/pkgconfig/
./configure_cmake.sh --prefix=/opt/snort

noah@snort16x64:~/snort_src/snort3/extra/build$ ls -l
/opt/snort/lib/pkgconfig/
total 4
-rw-r--r-- 1 root root 776 Mar 19 18:58 snort.pc


however, this is still an issue if you use --prefix=/ (see point 4 below)

//---------------------------------------------------------------------------------
3. Additional question -> will DAQ go to cmake in the future?

just curious.

//---------------------------------------------------------------------------------
4.  installation of snort binary when prefix = /

I've verified that when you set the prefix to the root of the system, it
installs everying under /usr
The commands i ran:
cd ~/snort_src
git clone git://github.com/snortadmin/snort3.git
cd ~/snort_src/snort3
./configure_cmake.sh --prefix=/
cd build
make
sudo make install

some output from sudo make install (everything shouldn't be going to /usr
here, unless i misunderstand how things work):
install the project...
-- Install configuration: ""
-- Installing: /usr/lib/pkgconfig/snort.pc
-- Installing: /usr/bin/snort
-- Installing: /usr/include/snort/actions/actions.h
-- Installing: /usr/include/snort/codecs/codec_module.h
-- Installing: /usr/include/snort/detection/detect.h
-- Installing: /usr/include/snort/detection/detection_engine.h


additionally, back to issue #2, when trying to install snort-extras using
--prefix=/, and pointing PKG_CONFIG_to the location where snort.pc is
installed, i get the same error:

cd extra/
export PKG_CONFIG_PATH=/usr/lib/pkgconfig/
./configure_cmake.sh --prefix=/
cd build
make

noah@snort16x64:~/snort_src/snort3/extra/build$ make

make: *** [all] Error 2

I also tried using --prefix-/usr, since that's where everything was
installed, but still recieved the above error.

All testing for the above errors was on Ubuntu 16 x64

Thank you,
Noah
