| 23 | INSTALLATION INSTRUCTIONS: | |
| 24 | ||
| 25 | The Cygwin lttng-ust port should be installed by carefully following the | |
| 26 | outlined instructions below: | |
| 27 | ||
| 28 | * lttng-ust | |
| 29 | ||
| 30 | - Start a Cygwin shell. | |
| 31 | ||
| 32 | - Download lttng-ust sources: | |
| 33 | ||
| 34 | git clone git://git.lttng.org/lttng-ust.git -b cygwin-2.0-experimental | |
| 35 | ||
| 36 | - Change directory and run the bootstrap script: | |
| 37 | ||
| 38 | cd lttng-ust | |
| 39 | ./bootstrap | |
| 40 | ||
| 41 | - Run the configure script with these parameters: | |
| 42 | LDFLAGS="-no-undefined" ./configure --prefix=/usr | |
| 43 | ||
| 44 | - Run the make command and install lttng-ust | |
| 45 | make | |
| 46 | make install | |
| 47 | ||
| 48 | INSTRUMENTATION: | |
| 49 | ||
| 50 | Refer the to the lttng-ust(3) man page | |
| 51 | (Online version: http://lttng.org/files/doc/man-pages/man3/lttng-ust.3.html). | |
| 52 | ||
| 53 | CYGWIN PORT LIMITATIONS: | |
| 54 | ||
| 55 | - Since Cygwin doesn't support file descriptor passing over UNIX socket, | |
| 56 | the SHMs (shared memory) and wait pipes are exposed via the filesystem in | |
| 57 | /tmp/lttng-fds. This is a potential security issue. | |
| 58 | ||
