Configure the Lazarus development environment in Ubuntu

Lazarus is a free Pascal-Based Visual Development Environment similar to Delphi. It can work in Linux and complete software development in Linux. Due to the large number of packages required, problems may also occur during installation. Therefore, I would like to make a summary here for future reference. First, download andIn orderInstall the following Deb package. Fp-units-rtl_2.2.0-1_i386.deb Fp-compiler_2.2.0-1_i386.deb Fpc-src_2.2.0-071107_i386.deb Fp-ide_2.2.0-1_i386.deb Fp-units-base_2.2.0-1_i386.deb Fp-units-db_2.2.0-1_i386.deb Fp-units-fcl_2.2.0-1_i386.deb Fp-units-fv_2.2.0-1_i386.deb Fp-units-gfx_2.2.0-1_i386.deb Fp-units-gtk_2.2.0-1_i386.deb Fp-units-gtk2_2.2.0-1_i386.deb Fp-units-i386_2.2.0-1_i386.deb Fp-units-misc_2.2.0-1_i386.deb Fp-units-multimedia_2.2.0-1_i386.deb Fp-utils_2.2.0-1_i386.deb Fp-units-gnome1_2.2.0-1_i386.deb Sudo apt-Get install libcurl3-dev Fp-units-net_2.2.0-1_i386.deb Lazarus_0.9.24-0_i386.deb Note the sentence marked in blue. This code is executed in terminal to install libcurl-Dev. With this component, you can continue to install the FP-units-Net package. After the installation is complete, you can create a new launcher from the desktop to point it to the/usr/bin/startlazarus file. In this way, a launcher can be started directly from the desktop, which is equivalent to a shortcut. As you can see, it is almost the same as Delphi, and many Delphi controls can be installed on it with slight modifications, which makes Lazarus rich in controls. Finally, let's talk about the program compression problem. Due to the compression ratio of FP-compiler, the size of compiled programs is huge, and an empty form can reach 14 Mb, this is a very bad thing. Lazarus provides a strip tool to compress programs. Run the following command: CD/usr/bin Strip/home/rarnu/proj/project1 The content after strip is your program path. Note that it must be the complete path. After compression, the original 14 m program has changed to 2 m Of course, a blank window of 2 Mb is unacceptable. If you want a smaller program, you can use Kol Kol already has the special Lazarus version. For details about how to use it, refer to my previous articles (click to enter) Using Kol in Lazarus is exactly the same as using Kol in delphi2007.
