安装

From Source Code¶

Install Dependences¶

Fedora/RHEL/AlmaLinux¶

On RHEL like linux distrobution, manage packages with rpm and dnf/yum.

# RHEL like distributions need epel-release, Fedora don't.
$ sudo dnf install -y epel-release
$ sudo dnf groupinstall -y "Development Tools" "Development Libraries"
$ sudo dnf install -y \
    binutils-devel \
    capstone-devel \
    cmake \
    elfutils-devel \
    elfutils-libelf-devel \
    gcc \
    gcc-c++ \
    glibc-devel \
    libunwind-devel

Debian/Ubuntu¶

On Debian like linux distrobutions, manage packages with apt.

$ sudo apt install -y build-essential
$ sudo apt install -y \
    cmake \
    gcc \
    binutils-dev \
    libc6 \
    libcapstone-dev \
    libelf-dev \
    libunwind-dev

If you want to compile the website, install

$ sudo apt install -y mkdocs

Compile¶

$ git clone https://github.com/rtoax/ulpatch
$ cd ulpatch
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr \
    -DCONFIG_BUILD_TESTING=OFF \
    -DCONFIG_BUILD_ULFTRACE=OFF \
    -DCONFIG_BUILD_ULTASK=OFF \
    ..
$ make -j$(nproc)

Or you could specify -B build argument of cmake, like cmake -B build -DCMAKE_BUILD_TYPE=Release.

CMake Macros¶

CMAKE_BUILD_TYPE¶

You can specify CMake Build type with CMAKE_BUILD_TYPE, such as -DCMAKE_BUILD_TYPE=Debug(Release,Debug,RelWithDebInfo,MinSizeRel), such as:

$ cmake -DCMAKE_BUILD_TYPE=Debug ..

Default is Debug.

CONFIG_BUILD_PIE_EXE¶

Build all executions as PIE(Position-Independent-Executable), such as:

$ cmake -DCONFIG_BUILD_PIE_EXE=1 ..

This cmake option is helpful if you want to test the PIE elf.

CONFIG_BUILD_TESTING¶

You can specify CONFIG_BUILD_TESTING to determine compile ulpatch_test or not, default ON. If you want to turn it off, such as:

$ cmake -DCONFIG_BUILD_TESTING=0 ..

CONFIG_BUILD_ULFTRACE¶

You can specify CONFIG_BUILD_ULFTRACE to determine compile ulftrace or not, default ON. If you want to turn it off, such as:

$ cmake -DCONFIG_BUILD_ULFTRACE=0 ..

CONFIG_BUILD_ULTASK¶

You can specify CONFIG_BUILD_ULTASK to determine compile ultask or not, default ON. If you want to turn it off, such as:

$ cmake -DCONFIG_BUILD_ULTASK=0 ..

CONFIG_BUILD_MAN¶

You can specify CONFIG_BUILD_MAN to determine compile manual pages of ULPatch or not, default ON. If you want to turn it off, such as:

$ cmake -DCONFIG_BUILD_MAN=0 ..

CONFIG_CAPSTONE¶

CMake CONFIG_CAPSTONE determine compile with capstone or not, default ON. If you want to turn it off, such as:

$ cmake -DCONFIG_CAPSTONE=OFF ..

CONFIG_LIBUNWIND¶

CMake CONFIG_LIBUNWIND determine compile with libunwind or not, default ON. If you want to turn it off, such as:

$ cmake -DCONFIG_CAPSTONE=OFF ..

If CONFIG_LIBUNWIND=ON(default), and your system donesn's have it, cmake will run fatal and tell you.

Install¶

$ sudo make install

Uninstall¶

$ sudo make uninstall

From RPM Package¶

Download¶

Download rpm packages from Release page.

Install¶

Then, use rpm or dnf command to install the rpm packages.

$ sudo dnf install ulpatch-*.rpm

Or

$ sudo rpm -ivh ulpatch-*.rpm

Build RPM Packages Your Own¶

Only support rpm management software system, such as Fedora, RHEL and its derivatives.

You need to install the rpm-build depends package.

$ sudo dnf install rpm-build

Then, install the depends of ulpatch according to spec:

$ sudo dnf builddep ulpatch.spec

Now, you can compile with rpmbuild. In the root directory of this project, I have written an rpmbuild(rpmbuild.sh) example for you. And of course, you need to archive the source code to tar package.

Generate tar archive:

$ ./archive.sh

Build the RPM packages:

$ ./rpmbuild.sh
