Cannot compile with latest components.

[maxolasersquad]

I am running Ubuntu 14.04 and following the instructions at http://manual.seafile.com/build_seafile/server.html

I download the following:

• ccnet-4.0.6-server
• libsearpc-3.0.3-server
• seafile-4.0.6-server
• seahub-4.0.6-server

I was able to succussefully make and install ccnet and libsearpc, but when I try to compile seahub I get the following.

/usr/local/lib/libevhtp.a(evhtp.c.o): In function `_evhtp_accept_cb':

This is a recent change. When building libevhtp, you need to run cmake -DEVHTP_DISABLE_SSL=OFF -DEVHTP_BUILD_SHARED=ON . instead of cmake . I'll update the document.

That did it. Thanks for the update.

I have the same problem with 4.1.2, but I'm using the build script build-server.py. What do I have to change there to compile it successfully?

Hi,
One year after, I have the same problem :

evhtp.c:(.text+0x4ef0): undefined reference to `bufferevent_openssl_socket_new'
collect2: error: ld returned 1 exit status
Makefile:611: recipe for target 'seaf-server' failed

I used the version 1.1.6 of libevhtp, and seafile-server-6.6.1. And I did compile libevhtp with the -DEVHTP_DISABLE_SSL=OFF -DEVHTP_BUILD_SHARED=ON flags.

Any idea ?

@lvedie There is a bug in recent libevhtp versions that the configure flag has been changed from -DEVHTP_BUILD_SHARED=ON to -DBUILD_SHARED_LIBS=ON.

See Yellow-Camper/libevhtp#145

This is a recent change. When building libevhtp, you need to run cmake -DEVHTP_DISABLE_SSL=OFF -DEVHTP_BUILD_SHARED=ON . instead of cmake . I'll update the document.

Btw, the current build instructions say exactly the opposite:

cmake -DEVHTP_DISABLE_SSL=ON -DEVHTP_BUILD_SHARED=OFF .

I am quite certain that we need shared libraries to link against and probably also want to have openssl support enabled, so please update the build instructions if they're wrong.
