build of version 1.7.1 fails

[omerbrandis]

hello,

I'm unable to perform Drogon installattion:

git clone https://github.com/an-tao/drogon - works cd drogon - works but git submodule update --init failed with : fatal: reference is not a tree: 4ec01750b0e8a77c1e118e99dbbe4da38df1ffbd Unable to checkout '4ec01750b0e8a77c1e118e99dbbe4da38df1ffbd' in submodule path 'trantor'

please advise. Omer.

Weird. I can run the exact commands without problem. Are you cloning into a empty directoy? Which OS are you using? And please try deleting the entire drogon directory and try again.

i also tried following trantor's installation instructions to "manually" install it under drogon/trantor. trantors build worked, but drogon's cmake failed with "You have called ADD_LIBRARY for library trantor without any source files."

[marty1885]

Do you mean the following failed?

git clone https://github.com/an-tao/drogon 
cd drogon
git clone https://github.com/an-tao/trantor
mkdir build
cd build
cmake ..
make

[omerbrandis]

I've tried git clone https://github.com/an-tao/drogon cd drogon rm -r trantor git clone https://github.com/an-tao/trantor cd trantor cmake -Bbuild -H. cd build make -j cd .. mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release .. failed with "You have called ADD_LIBRARY for library trantor without any source files."

[marty1885]

I've contacted Github support asking what's going on, Likely their CDN screwed up and have to wail until the cache expires.

Please try:

git clone https://github.com/an-tao/drogon 
cd drogon
rm -r trantor
git clone https://github.com/an-tao/trantor
mkdir build
cd build
cmake ..
make

[omerbrandis]

tried the latest suggestion , hasn't solved the problem. still getting

try to remove your drogon clone first.

assuming you're on $HOME

sudo rm -rf drogon

---

then,

git clone https://github.com/drogonframework/drogon
cd drogon
git submodule update --init
mkdir build && cd build
sudo cmake ..
sudo make && sudo make install

---

then try

drogon_ctl -v

I'm not sure with Ubuntu 16 anyway

[prothegee]

I just tested,

Ubuntu 18.04 also unable to build with sudo cmake -DCMAKE_BUILD_TYPE=Release ..

But Debian 10 (buster) & Ubuntu 20.04 (focal) are able to build with Release type.

Surprisingly, my windows 10 are unable to use Debug type, but able to build with Release type (ninja build)

#993 Should fix the std::filesystem error on Ubuntu 18.04.
