If you run bitcoind first time, it will cost hours to download the block chain. In this process it won't output useful information such as downloading progress or downloaded block count. So how could we know how much time remaining to finish the downloading?
We can use following command to get downloaded block count:
bitcoind getblockcount
And we can get the latest block number of bitcoin network by visiting this url: http://blockexplorer.com/q/getblockcount
Download latest source code from github, following is its dependencies:
| Library Name | Use |
|
libevent |
Event-driven async I/O |
|
libmemcached |
memcached client |
|
pthreads |
POSIX threads |
|
zlib |
gzip compression |
|
jansson |
JSON |
|
OpenSSL's libcrypto |
sha256 |
|
libcurl |
HTTP client |
it contains OpenSSL's libcryptoa file named "autogen.sh" which is generated by autotools
pakcage name mapping for apt-get:
jansson -> libjansson
OpenSSL -> libssl-dev
First, we need run "autogen.sh" first
./autogen.sh
If you got following error message, you need install libcurl first
configure.ac: error: possibly undefined macro: AC_MSG_ERROR
Following is the command to install libcurl:
apt-get install libcurl4-gnutls-dev
If you run autogen.sh before libcurl-dev and libmysqld-dev is installed, you will get following error in "configure" progress:
|
1 2 |
./configure: line 4830: syntax error near unexpected token `,' ./configure: line 4830: `LIBCURL_CHECK_CONFIG(, 7.10.1, , |
You need install libcurl and re-run autogen.sh
And following error will occur in "make" progress:
server.c:106:2: error: #error ("No valid database engines defined")
make[1]: *** [server.o] Error 1
Then you should install libmysqld-dev and re-run autogen.sh
After above error is fixed, we can compile pushpool in "configure -> make -> make install" workflow.
