cURLpp not found on Debian 9.0 about pf_lidar_ros_driver

[ipa-hsd]

That is strange because the key for debian is libcurlpp-dev as seen here. I don't think libcurl4-openssl-dev is the same package so you are bound to get No such file or directory error. Are you sure you have done

sudo apt-get update
rosdep update

[wsaihopfsg]

Yes I have performed both commands.

While libcurlpp-dev was not found, this was the message for sudo apt-get install libcurl-dev, and subsequently I chose libcurl4-openssl-dev

Package libcurl-dev is a virtual package provided by:
  libcurl4-openssl-dev 7.52.1-5+deb9u12
  libcurl4-nss-dev 7.52.1-5+deb9u12
  libcurl4-gnutls-dev 7.52.1-5+deb9u12
You should explicitly select one to install.

This is the package information for libcurlpp-dev in Debian, which depends also on libcurl4-openssl-dev

These are some of the commands I used:

$ dpkg -l | grep curl

ii  curl                                            7.68.0-1ubuntu2.2                           amd64        command line tool for transferring data with URL syntax

ii  libcurlpp-dev:amd64                             0.8.1-2build2                               amd64        c++ wrapper for libcurl (development files)
ii  libcurlpp0:amd64                                0.8.1-2build2                               amd64        c++ wrapper for libcurl
ii  ros-foxy-libcurl-vendor                         2.3.3-1focal.20201006.191618                amd64        Wrapper around libcurl, it provides a fixed CMake module and an ExternalProject build of it.

So the full name of the library I am looking for is libcurlpp-dev. Next list all the files associated with this lib

$ dpkg -L libcurlpp-dev

You can see that there is /usr/include/curlpp/cURLpp.hpp listed, which we want to include in the code. For these files to be found, I check the .pc file

$ cat /usr/lib/x86_64-linux-gnu/pkgconfig/curlpp.pc

# This is a comment
prefix=/usr
exec_prefix=/usr
includedir=include

Name: curlpp
Description: cURLpp is a libcurl C++ wrapper
Version:                            
Libs: -Llib/x86_64-linux-gnu -lcurlpp -Wl,-Bsymbolic-functions -Wl,-z,relro 
Cflags: -Iinclude 
# libcurl is required as non-private because CurlHandle.inl uses curl_easy_setopt.
Requires: libcurl

Based on this I include curlpp (Name:) in my CMakeLists.txt

Not sure if it was a typo, but the command you typed: sudo apt-get install libcurl-dev. Shouldn't it be libcurlpp-dev?

[ipa-hsd]

The file associated with libcurl4-openssl-dev as seen here is /usr/include/i386-linux-gnu/curl/curl.h. I am guessing this is a C implementation and not C++. So either find a corresponding C++ implementation for debian or change the code to use the C api.

[wsaihopfsg]

curlpp-dev is indeed not available for Debian 9 (Stretch).

Thanks for your help.
